In the Figure given below two masses m and m' are tied with a thread passing over a pulley, m' is on a frictionless horizontal surface. If acceleration due to gravity is g, the acceleration of m' in this arrangement will be:

a
g
b
mg/(m + m')
c
mg/m'
d
mg/(m - m')

detailed solution

Correct option is B

Acceleration = Net force in the direction of a Total mass =mgm+m′
