Assertion and Reasoning Questions on Force for ICSE Class 10 Physics
Assertion and reasoning questions are also known as assertion reason questions. Assertion-Reason questions are a type of question format used in ICSE exams where two statements are provided: an Assertion (A) and a Reason (R). Students need to determine whether each statement is true or false and if the Reason correctly explains the Assertion.
Directions:
(a) Both assertion and reason are true.
(b) Both assertion and reason are false.
(c) Assertion is false but reason is true.
(d) Assertion is true but reason is false.
Q. 1. Assertion: In uniform circular motion, the particle has some acceleration.
Reason: Centripetal force is essential to keep a particle in circular motion.
Ans. (c) Assertion is false but reason is true.
Explanation:
In uniform circular motion the magnitude of the acceleration is constant, but direction always keep on changing, which results in non-zero acceleration when a particle moves in a circular motion, centripetal force is always acted upon it.
Q. 2. Assertion: The turning effect on the body about an axis is due to the moment of force (or torque) applied on the body.
Reason: The SI unit of moment of force is N-m.
Ans. (a) Both assertion and reason are true.
Explanation:
The body rotates due to the moment of force about the pivoted point and unit of moment of force unit of force
unit of distance.
Q. 3. Assertion: Equilibrium means either the body is at rest (static equilibrium) or in uniform motion (dynamic equilibrium).
Reason: When the resultant force is zero or there is no unbalanced force, the body is said to be in equilibrium.
Ans. (a) Both assertion and reason are true.
Explanation:
In equilibrium, a body is at rest or in uniform motion. When the body is in equilibrium there is no unbalanced force.
Q. 4. Assertion: The moon revolving around the Earth is in dynamic equilibrium.
Reason: For a body to be in equilibrium the resultant of all the forces acting on the body should be positive.
Ans. (d) Assertion is true but reason is false.
Explanation:
Moon is in dynamic equilibrium around the Earth because it is in state of motion, under the influence of the several forces. And body to be in equilibrium, all the forces acting on the body should be equal to zero.
Q. 5. Assertion: Centripetal and centrifugal forces don’t act at the same time.
Reason: In circular motion, the centripetal and centrifugal force acting in opposite direction balances each other.
Ans. (b) Both assertion and reason are false.
Explanation:
While moving along a circle, the body has constant tendency to move in a natural straight line path. Due to which the centrifugal force arises. The centrifugal force does not act on the body in motion, the only force acting on the body in motion is centripetal force. The centrifugal force acts on the source of centripetal force to displace it radially outward from centre of the path. So, both are incorrect.
Q. 6. Assertion: Centrifugal force is a real force that pushes an object away from the center of a circular path.
Reason: Centrifugal force is a pseudo force that arises in a rotating frame of reference. A
Ans: (c) Assertion is false, but Reason is true.
Q. 7. Assertion: Centripetal force is necessary to keep an object moving in a circular path.
Reason: Centripetal force provides the necessary centripetal acceleration to change the direction of the velocity of the object.
Ans. (a) Both Assertion and Reason are true.
Q. 8. Assertion: The work done by the centripetal force on an object moving in a circular path is zero.
Reason: The direction of the centripetal force is perpendicular to the direction of the displacement of the object.
Ans: (a) Both Assertion and Reason are true.
Q. 9. Assertion: The kinetic energy of an object moving in a circular path remains constant.
Reason: The speed of the object remains constant.
Answer: (a) Both Assertion and Reason are true.

Frequently Asked Questions (FAQs) on Force ICSE Class 10 Physics Assertion and Reasoning Questions
Q1: What are Assertion and Reasoning questions?
A1: Assertion and Reasoning questions are a type of question format used in ICSE exams where two statements are provided: an Assertion (A) and a Reason (R). Students need to determine whether each statement is true or false and if the Reason correctly explains the Assertion.
Q2: How do Assertion Reasoning questions differ from other question types?
A2: Unlike multiple-choice questions, Assertion-Reason questions require students to analyze the relationship between two statements. It’s not just about knowing the facts but understanding how they connect logically.
Q3: What steps should I follow to correctly answer Assertion and Reasoning questions?
A3: Follow these steps:
Read both statements carefully. Understand what each statement is saying.
Determine the truth value of each statement. Decide if each statement is true or false independently.
Analyze the relationship. If both statements are true, decide whether the Reason (R) correctly explains the Assertion (A).
Choose the correct option. Based on your analysis, select the appropriate answer from the given options.
Q4: What options are typically provided for Assertion and Reasoning questions?
A4: The typical options are:
A. Both A and R are true, and R is the correct explanation of A.
B. Both A and R are true, but R is not the correct explanation of A.
C. A is true, but R is false.
D. A is false, but R is true.
Q5: What should I check to determine if the Reason correctly explains the Assertion?
A5: Ensure that the Reason provides a logical explanation for the Assertion. Check if the Reason directly addresses the cause or basis of the Assertion and if they are contextually linked.
Q6: How can I improve my skills in answering Assertion and Reasoning type questions?
A6: Practice regularly with sample questions and past papers. Focus on understanding the concepts thoroughly rather than rote memorization. Analyzing how different facts and concepts interrelate will enhance your ability to correctly answer these questions.
Q7: What are common mistakes to avoid when answering Assertion and Reasoning questions?
A7: Common mistakes include:
Not reading the statements carefully and missing key details.
Assuming the Reason explains the Assertion without checking the logical connection.
Confusing the order or relationship between the statements.
Overthinking and adding information not provided in the question.
Q8: What resources can help me practice Assertion and Reasoning questions for ICSE Class 10 Physics?
A8: Use study guides specifically designed for Assertion-Reason questions. Online educational platforms and reference books for ICSE Class 10 Physics also offer practice questions and explanations. xamcontent.com/cisce also provides assertion reason questions for ICSE Class 10 Physics.
