Determine tension `T_(4)` (in N) in fig.

A

`T_(4)=25 N`

B

`T_(4)=50 N`

C

`T_(4)=300 N`

D

`T_(4)=200 N`

Text Solution

Verified by Experts

The correct Answer is:
D
The free body diagram is drawn so that only the string `T_(4)` is cut, as shown in fig.
`Sigma F_(y)=0`
`implies T_(4) cos 60^(@)=100`
`implies T_(4)=200 N`
