In the figure shown neglecting friction ...

In the figure shown neglecting friction and mass of pulley, what is the acceleration of mass `B` ?

A

`(g)/(3)`

B

`(5g)/(2)`

C

`g`

D

`(2g)/(5)`

Text Solution

Verified by Experts

The correct Answer is:
D
From constraint relation , if acceleration of mass `B` is a then acceleration of mass `A` will be `a//s:`
`FBD` of `A:`
`T-mg=(ma)/(2)` …….`(i)`

`FBD` of `B:`
`mg-(T)/(2)=ma` …..`(ii)`

From `(i) & (ii)` ,br. `a=(2g)/(5)`
