Question

Four co-planar concurrent forces are acting on a body as shown in the figure to keep it in equilibrium. The the values of P and `theta` are.

A. `P=4N,theta=0^(@)`
B. `P=2N,theta=90^(@)`
C. `P=2N,theta=0^(@)`
D. `P=4N,theta=90^(@)`

Answer 1

Correct Answer - B
`P cos theta+sqrt(3)=2 sin 60^(@)`
`P sin theta=1+2 cos 60^(@)`
