The angles between P+Q and P-Q will be

Given that P 12, Q = 5 and R = 13 also P+Q=R, then the angle between P and Q will be

Given that P 12, Q = 5 and R = 13 also P+Q=R, then the angle between P and Q will be

Three forces P,Q and R are acting at a point in the plane. The angle between P & Q and Q & R are 150^(@) & 120^(@) respectively, then for equilibrium, forces P,Q & R are in the ratio

Three forces P,Q and R are acting at a point in the plane. The angle between P & Q and Q & R are 150^(@) & 120^(@) respectively, then for equilibrium, forces P,Q & R are in the ratio

The resultant of two forces P and Q makes an angle of 30^(@) with P. What is the angle between P and Q, if the magnitude of the resultant is equal to Q sqrt(3) ?

Three forces P, Q and R are acting on a particel in the plane, the angle between P and Q and that between Q and R are 150^(@) and 120^(@) respectively. Then for equilibrium, forces P, Q and R are in the ratio
