Q: In the following figure, the pulley is massless and frictionless. There is no friction between the body and the floor. The acceleration produced in the body when it is displaced through a certain distance with force ‘P’ will be

Numerical

(a) P/M

(b) P/2M

(c) P/3M

(d) P/4M

Ans: (b)

Sol:Let T = tension in the string

P = 2 T …(i)

T = M a …(ii)

From (i) and (ii)

a = P/2M
