A ball of mass m moving with velocity v,...

A ball of mass `m` moving with velocity `v`, collide with the wall elastically as shown in the figure. After impact the change in angular momentum about `P` is :
.

A

`(sqrt(3))/(2) mvd`

B

mvd

C

`sqrt(3) mvd`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A

Change in Angular momentum,
`DeltaL = (DeltaP) (d)/(2) = 2mv cos 30 (d)/(2) = (mvd sqrt3)/(2)`
