The given system is in equilibrium. The blocks are at same horizontal level. The value of angle is : `theta` is :

A

`tan^(-1)3/7`

B

`tan^(-1)2/3`

C

`tan^(-1)5/4`

D

`tan^(-1)9/7`

Text Solution

Verified by Experts

The correct Answer is:
b
`T_(1) cos theta =T_(2)`
`T_(1) sin theta 20`
|`T_(3) cos 53^(@)=T_(2)`|
`T_(3) sin 53^(2)=40`
`tan theta =2/3 rarr theta = tan^(-1) 2/3`
