Consider the situation shown in the figure.

Find acceleration of B.

A

`(g)/(7)`

B

`(2g)/(7)`

C

`(3g)/(7)`

D

`(2g)/(5)`

Text Solution

Verified by Experts

The correct Answer is:
A
57(A)
2T - 50 = 5A, 40 - T = 4 (2a)
On solving these equations, we get
`a = (10)/(7) m//s^(2)` or `(g)/(7)`
and `2a = (20)/(7) m//s^(2)` or `(2g)/(7)`
