answered-by-expert Expert Answer
Torque= Moment of inertia * angular acceleration
 
Moment of inertia is given and 
 
angular acceleratio= (150-0)/ 10= 15 rad/s2
 
put the values and get the answer.

A Uniform Disc of diameter R/2 is put over another uniform disc of radius R of same thickness and Density. The peripheries of the two discs touch each other. The Centre of Mass of the system from centre of the big disc is? (I asked this question before but the answer was wrong. They took the Radius as R/2 while it is the Diameter)
