Fig. shows a block of mass `m_(1)` resting on a smooth surface. It is connected to a mass `m_(2)` by a string passing over a massless and frictionaless pulleys `m_(2) gt m_(1)`. The acceleration of the hanging mass `m_(2)` is `:`

Text Solution

Verified by Experts

The correct Answer is:
D

`T=m_(1)" ….(1) "m_(2)g-T=m_(2)a" …….(2)"`
add equation (1) and (2)
`a=(m_(2)g)/(m_(1)+m_(2))`
