Two balls having masses m and 2m are fasrtened to two light strings of same length (figure). The other ends of the strings are fixed at O. The strings are kept in the same horizontal line and the system is released from rest. The collision between the balls is elastic. Point A is the lowest point at which either ball can reach

The position at which the balls will collide for the first time

A

at point A

B

left of point A

C

right of point A

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A

Initially speed of both balls is zero. Further. Tangential acceleration of both balls at any time are same. Hence before the first time intervals.
Hence both of them shall collide at A,
