In the pulley system shown, if radii of the bigger and smaller pulley are `2 m` and `1 m` respectively and the acceleration of block `A` is`5 m//s^2` in the downward direction, then the acceleration of block `B` will be :
.

A

`0ms^(-2)`

B

`5ms^(-2)`

C

`10ms^(-2)`

D

`5/2ms^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
D
Given `alpha_(A)=2alpha=5m/s^(2)impliesalpha=5/2m//s^(2)`
Hence accelerationn of `B`, `a_(B)=1(alpha)=5/2m//s^(2)`
