Projection Under uniform Acceleration

Question

Assertion : When a body is dropped or thrown horizontally from the same height, it would reach the ground at the same time.
Reason : Horizontal velocity has no effect on the time taken.

Moderate

A

If both assertion and reason are true and reason is a true 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.

Solution

Both bodies will take same time to reach the earth because vertical downward component of velocity for both the bodies will be zero and time of decent
$t = \sqrt{\frac{2 h}{g}}$ Horizontal velocity has no effect on the vertical direction.
