In the fig. given masses m and m' are tied with a tread 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

m'g/(m+m)

C

mg/m'

D

mg/(m-m)

Text Solution

Verified by Experts

The correct Answer is:
B
`mg-T=m'a`
T=ma
`therefore a=(m'g)/((m+m))`
