(a) Null vector
(b) Scalar
(c) Same vector
(d) Double vector

Show Answer

Answer: (a)
Explanation: The sum of a vector and its negative results in a null or zero vector.

(a) 5
(b) 7
(c) 12
(d) 1

Show Answer

Answer: (a)
Explanation: Magnitude = √(Ax2 + Ay2) = √(9 + 16) = 5.

Q8. The unit vector along a vector A is given by:
(a) A/|A|
(b) |A|/A
(c) A²/|A|
(d) A/2

Show Answer

Answer: (a)
Explanation: Unit vector = vector / magnitude.

Q9. If the angle between two vectors is 90°, then their scalar product is:
(a) Maximum
(b) Minimum
(c) Zero
(d) Negative

Show Answer

Answer: (c)
Explanation: Scalar product = AB cosθ; cos90° = 0.

Q10. A particle is projected with velocity v at angle θ. The range is maximum when:
(a) θ = 30°
(b) θ = 45°
(c) θ = 60°
(d) θ = 90°

Show Answer

Answer: (b)
Explanation: Range is maximum when sin2θ is maximum, which occurs at θ = 45°.

Q11. In projectile motion, the horizontal component of velocity:
(a) Changes due to gravity
(b) Remains constant
(c) Increases continuously
(d) Decreases continuously

Show Answer

Answer: (b)
Explanation: There is no acceleration in horizontal direction, so the horizontal component of velocity remains constant.

Q12. At the highest point of projectile motion, the velocity is:
(a) Zero
(b) Maximum
(c) Horizontal
(d) Vertical

Show Answer

Answer: (c)
Explanation: At the maximum height, vertical component becomes zero and only horizontal component remains.

Q13. The shape of the trajectory of a projectile is a:
(a) Circle
(b) Ellipse
(c) Parabola
(d) Hyperbola

Show Answer

Answer: (c)
Explanation: The path of a projectile is a parabola due to the quadratic dependence on time.

Q14. Which of these quantities remains constant in projectile motion?
(a) Total velocity
(b) Vertical velocity
(c) Horizontal velocity
(d) Acceleration in y-direction

Show Answer

Answer: (c)
Explanation: Only horizontal velocity remains constant during projectile motion.

Q15. Which component of projectile motion changes uniformly?
(a) Horizontal velocity
(b) Vertical velocity
(c) Acceleration
(d) None

Show Answer

Answer: (b)
Explanation: Vertical velocity changes uniformly due to constant acceleration g.

Q16. Centripetal acceleration always acts:
(a) Outward
(b) Along velocity
(c) Along radius outward
(d) Towards the center

Show Answer

Answer: (d)
Explanation: Centripetal acceleration always acts towards the center of the circular path.

Q17. The direction of instantaneous velocity in circular motion is:
(a) Along radius
(b) Towards center
(c) Along tangent
(d) Opposite to radius

Show Answer

Answer: (c)
Explanation: Instantaneous velocity is always tangential to the circular path.

Q18. The angular speed in uniform circular motion is:
(a) Increasing
(b) Decreasing
(c) Constant
(d) Zero

Show Answer

Answer: (c)
Explanation: Angular speed remains constant in uniform circular motion.

Q19. The range of a projectile depends on:
(a) Only mass
(b) Initial speed and angle of projection
(c) Height only
(d) Time of flight only

Show Answer

Answer: (b)
Explanation: Range = (v² sin 2θ)/g depends on initial speed and angle.

Q20. In uniform circular motion, if the speed is doubled, the centripetal acceleration becomes:
(a) Doubled
(b) Four times
(c) Halved
(d) One fourth

Show Answer

Answer: (b)
Explanation: Centripetal acceleration a = v²/R, so if v is doubled, a becomes 4 times.
