Questions
Two blocks A and B of masses 2m and m, respectively are connected by a massless and inextensible string. The whole system is suspended by a massless spring with the block A above block B . The magnitudes of acceleration of A and B immediately after the string is cut, are respectively:
detailed solution
Correct option is B
After string is cut, free body diagram of block A gives2maA = 3mg-2mg or aA = mg2m = g2Free body diagram of block B givesmaB = mg or aB = gSimilar Questions
A constant force F = m2g/2 is applied on the block of mass m1 as shown. The string and the pulley are light and the surface of the table is smooth. Find the acceleration of m1.
