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

A

`(g)/(3)`

B

`(5g)/(2)`

C

`(2g)/(2)`

D

`(2g)/(5)`

Text Solution

Verified by Experts

The correct Answer is:
D

For block `A` ,
`mg-2T=ma` (1)
For block `B` , `T-mg=mb` (2)
And by constraint motion,
`(a-b)+a=0` (3)
Solving (1), (2) and (3) get
`a=-g//5`
and `b=-2g//5` .
