(P, Q ) and (R ) are three coplanar forces acting at a point and are in equilibium. Given : (P=1.9318 ~kg ) wt ( [ ₁=0.9659 ] ), the value of (R ) (in ( kg ) wt) is

Step-by-step solution

Using Lami's theorem, we have aligned & P ₁ = R 150^ P ₁ = R (180^ -30^ ) & 1.9318 kgwt 0.9659 = R 1 / 2 & R= 1.9318 0.9659 1 2 kgwt =1 kgwt . aligned
