If `O` is at equilibrium then the values of the tension `T_(1)` and `T_(2)` are, (`20 N` is acting vertically downwards at `O`).

A

`20N,30N`

B

`20 sqrt3 N, 20N`

C

`20 sqrt3 N,20 sqrt3N`

D

`10N,30N`

Text Solution

Verified by Experts

The correct Answer is:
B
`T_(1)sin theta_(1) =T_(2) cos theta_(2),T_(1) cos theta_(1) =T_(2) sin theta_(2) +mg` .
