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 vertical direction.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.

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