Both the blocks shown in figure have same mass `'m'`. All the pulley and strings are massiess.

Options

A. Acceleration of block `A` is `(2g)/(5)`
B. Acceleration of block `A` is `(g)/(5)`
C. Acceleration of block `B` is `(g)/(5)`
D. Tension in the attached with `A` is `(3mg)/(5)`

Answer

`A, C, D`

Explanation

`mg-T=2ma` ......(i)
`2T-mg=ma` ......(ii)
Solving.
`mg=5ma`
`a=(g)/(5)`
`T=mg-2ma`
`=mg-2m(g)/(5)=(3mg)/(5)`
