If acceleration of `A` is `2m//s^(2)` to left and acceleration of `B` is `1m//s^(2)` to left, then acceleration of `C` is-

A

`1m//s^(2) upwards`

B

`1m//s^(2)downw`

C

`2m//s^(2) downwards`

D

`2m//s^(2)upwards`

Text Solution

Verified by Experts

The correct Answer is:
A
`l_(1) +l_(2) +l_(3) +2l_(4) =` constant
`(dl_(1))/(dt) +(dl_(2))/(dt) +(dl_(3))/(dt) +2(dl_(4))/(dt) = 0`
`(d^(2)l_(1))/(dt^(2)) +(d^(2)l_(2))/(dt^(2)) +(d^(2)l_(3))/(dt^(2)) +2(d^(2)l_(4))/(dt^(2)) = 0`

`2+(2-1) -1+2(d^(2)1_(4))/(dt^(2)) =0`
`a_(B) = - 1m//s^(2)`
`a_(B) = 1m//s^(2) uarr`
