2. My attempt-
I used torque=M.I*angular acceleration
I chose the axis to be perpendicular to the...
What is the initial acceleration of mass 5M .The pulleys are ideal and the string inextensible.

My attempt-
2Mg-T=2Ma (for 2M)
T=Ma (for M)
Solving we get T=2Mg/3
T-N=5MA (for 5M)
N=2MA (for 2M)
Solving we get A=2g/21
but the given...
