In the pulley-block arrangement shown in figure , find the relation between `a_(A),a_(B)` and `a_(C)`

A

`a_(A) + 2a_(B) 2a_(C ) = 0`

B

`a_(A) + 2a_(B) + a_(C ) = 0`

C

`2a_(A) + a_(B) + a_(C ) = 0`

D

`a_(A) + a_(B) + 2a_(c ) = 0`

Text Solution

Verified by Experts

The correct Answer is:
B
`X_(A) + 2X_(B) + X_(C )` = constant
On double differentiating with respect to time, we get, `a_(A) +`
