The bob `A` of a simple pendulum is released when the string makes an angle of `45^(@)` with the vertical. It hits another bob `B` of the same material and same mass kept at rest on the table. If the collision is elastic, then

A

Both A and B rise to the same height.

B

Both A and B come to rest at B

C

Both A and B move with the same velocity of A

D

A comes to rest and B moves with the velocity of A

Text Solution

Verified by Experts

The correct Answer is:
D
Due to the same mass of A and B as well as due to elastic collision, velocities of spheres get interchanged after the collision. So, A comes to rest and B moves with the velocity of A.

A simple pendulum is released from rest with the string in horizontal position. The vertical component of the velocity of the bob becomes maximum, when the string makes an angle theta with the vertical. The angle theta is equal to

A bob is attached to one end of a string other end of which is fixed at ped A . The bob is taken to a position where string makes an angle of 30^(@) with the horizontal. On the circular path of the bob in vertical plane there is a peg 'B' at a symmetrical position with respect to the position of release as shown in the figure. If V_(c) and V_(a) be the minimum speeds in clockwise and anticlokwise direction respectively, given to the bob in order to hit the peg 'B' then ratio V_(c) : V_(a) is equal to :
