Two blocks A and B of same mass m attach...

Two blocks A and B of same mass m attached with a light spring are suspended by a string as shown in fig. Find the acceleration of block A and B just after the string is cut.

Text Solution

Verified by Experts

When block A and B are in equilibrium position
F.B.D of 'B'

when string is cut tension T becomes zero. But spring does not change its shape just after cutting. So spring force acts on mass B, agai draw F.B.D of blocks A and B as shown in figure
F.B.D of 'B'
