Question

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:

Moderate

A

g
B

mg/(m + m')
C

mg/m'
D

mg/(m - m')

Solution

$Acceleration = \frac{Net force in the direction of a}{Total mass} = \frac{mg}{m + m^{'}}$
