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

`20sqrt3N,20N`

C

`20sqrt3N,20sqrt3N`

D

`10N,30N`

Text Solution

Verified by Experts

The correct Answer is:
B
`T_(1)sin 30^(@)=T_(2)cos 30^(@),T_(1)=sqrt3T_(2)....(1)`
`T_(1)cos 30^(@)=20+T_(2)` ...(2) , soving (1) and (2)
