Two masses 8 kg and 12 kg are connected ...

Two masses 8 kg and 12 kg are connected at the two ends of a light inextensible string that goes over a frictionless pulley. Find the acceleration of the masses, when the masses are released.

Text Solution

Verified by Experts

The correct Answer is:
T`- 8xx 10 = 8a, 12 xx 10 - T = 12 a`
i.e., a = 2m`cdot s^(-2)`, T = 96 N
