Assertion : A shell fired from a gun is moving along the parabolic path. If it explodes at the top of the trajectory, then no part of the shell can fly vertically.
Reason : The vertical momentum of the shell at the top of the trajectory is zero.

View answer and explanation

Correct option: D

Assertion is incorrect, reason is correct.

Option D is correct because the assertion is false; even if the vertical momentum is zero at the top, fragments can have vertical components after the explosion. The reason is correct; the vertical momentum of the shell is zero at the top.
