A fixed pulley of radius 20 cm and moment of inertia 0.32 kg.`m^(2)` about its axle has a massless cord wrapped around its rim. A mass M of 2 kg is attached to the end of the cord. The pulley can rotate about its axis without any friction. The acceleration of the mass M is :- (Assuming `g=10m//s^(2)`)
A. `1m//s^(2)`
B. `3m//s^(2)`
C. `2m//s^(2)`
D. `4m//s^(2)`
