Answer 1

Step-by-step explanation:

Solution :

In situation 1, the tension T has to hold both the masses 2m and m therefore,

T= 3mg

In situation 2, when the string is cut, the mass m is a freely falling body and its acceleration due to gravity is g. <br> For mass 2m, just after the string is cut, T remains 3mg because of the extension of string.

3m−2mg=2m×a

g/2=a
