Question

Two balls of different masses are thrown vertically upward with same speed. They will pass through their point of projection in the downward direction with the same speed. The maximum height and downward velocity attained at the point of projection are independent of the mass of the ball.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

If both assertion and reason are true and reason is the correct explanation of assertion

Answer 2

$h = ut - (1/2)gt^2$ and $v^2 = u^2 - 2gh$ The above equations are independent of mass
