P, Q and R are three coplanar forces acting at a point and are in equilibrium. Given `P= 1.9318 kg-wt, sin theta_(1)= 0.9659`, the value of R is `(in kg-wt)`

A

`P/(sinalpha)=Q/(sinbeta)=R/(singamma)`

B

`P/(cosalpha)=Q/(cosbeta)=R/(cosgamma)`

C

`P/(tan alpha)=Q/(tan beta)=R/(tangamma)`

D

`P/(sinbeta)=Q/(singamma)=R/(sinalpha)`
