A uniform disc of mass M =2.50 kg and radius `R = 0.20` m is mounted on an axle supported on fixed frictionless bearings. A light cord wrapped around the rim is pulled with a force 5 N. On the same system of pulley and string, instead of pulling it down, a body of weight 5 N is suspended. If the first processis termed A and the second B, the tangential acceleration of point P will be:
A. Equal in the processes A and B.
B. Greaterin process A than in B.
C. Greater in process Bthan in 4.
D. Independent of the two processes.
