Question

Two blocks A and B of masses 3 m and m respectively are connected by a massless and 1nextensible string. The whole system is suspended by a massless spring as shown in figure. The magnitudes of acceleration of A and B immediately after the string is cut, are respectively :-
  

Options

A.

g3,g

B.

g,g

C.

g3, g3

D.

g g3

Solution

Before cutting the strip :-

T = mg
After cutting the strip :-

aA=4mg-3mg3m=g3
aB=mgmg
