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.
✓

Answer

(a) 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 $t=\sqrt{\frac{2 h}{g}}$. Horizontal velocity has no effect on the vertical direction.
