C
g upwards, 2g downwards
D
2g upwards, g downwards

Text Solution

Verified by Experts
The correct answer is:
A

After string is cut, FBD of m

a = = g ↓

FBD of 2m (when string is cut tension in the spring takes finite time to become zero. However, tension in

the string immediately become zero.)
