A light thread has been tightly wrapped around a disc of mass M and radius R. The disc has been placed on a smooth table, lying flat as shown. The other end of the string has been attached to a mass `m` as shown. The system is released from rest. If `m = M`, which point of the disc will have zero acceleration, immediately after the system is released?

1.	A light thread has been tightly wrapped around a disc of mass M and radius R. The disc has been placed on a smooth table, lying flat as shown. The other end of the string has been attached to a mass `m` as shown. The system is released from rest. If `m = M`, which point of the disc will have zero acceleration, immediately after the system is released?
Answer» Correct Answer - A point at a distance `(R)/(2)` from centre
