In the arrangement shown in figure, string is light and inextensible and friction is absent every where. The speed of both blocks after the block `'A'` has ascend a height of `1m` will be `(g=10 m//s^(2))`

A

`2 m/s`

B

`2.58 m/s`

C

`3 m/s`

D

`3.58 m/s`

Text Solution

Verified by Experts

The correct Answer is:
`(2)`
`m_(B)gh = m_(A) gh + 1/2 m_(A) v^(2) + 1/2 m_(B) v^(2)`
