The bob $A$ of simple pendulum is released when the string makes an angle of $45^o$ 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
The bob $A$ of simple pendulum is released when the string makes an angle of $45^o$ 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 $A$

Two pendulums with identical bobs and lengths are suspended from a common support such that in rest position the two bobs are in contact (figure). After being displaced by $5^o $ the bob $A$ is released from rest, at $t = 0$ subsequently it collides elastically head-on with the other bob.The graph showing variation in energy of pendulum $A$ with time, for $0 \leqslant t \leqslant T$ (where $T$ is the period of either pendulum).
