When a body is projected at an angle with the horizontal in the uniform gravitational field of the earth the angular momentumof the body about the point of projection as it proceeds along its path _______ .

Answer»

Remains CONSTANT
Increases
DECREASES
Initially decreases and after HIGHEST point it increases

Solution :`vecL=vecrxxvecp=mvecrxxvecv`
L = rp sin `theta` = MVR sin `theta` = mr (V sin theta)
As vertical component of velocity (v sin `theta` ) initially decreases and after its highest point increases
`implies ` L, initially decreases and after highest point it increases.
