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 as shown in the figure. The magnitudes of acceleration of A and B immediately after the string is cut, are respectively
detailed solution
Correct option is B
Acceleration of B = g∵mas=mg⇒as=g For block A 2maA=mg acceleration of A is aA=g/2 aA=g/2Talk to our academic expert!
