A mass of 1kg is suspended by a string A. Another string C is connected to its lower end (see figure). If a sudden jerk is given to C, then

A

The portion AB of the string will break

B

The portion BC of the string will break

C

None of the strings will break

D

The mass will start rotating

Text Solution

Verified by Experts

The correct Answer is:
B
If a sudden jerk is given to C then it will experience tension due to inertia of rest of mass M. This force will not be transmitted to the string A and so the string C will break. Hence the portion BC of the string will brea
