The greatest and least magnitude of the resultant of two forces of constant magnitude are F and G. When the forces act an angle 2α, the resultant in magnitudesis equal to

The resultant of two force P N and 3 N is a force of 7 N.If the direction of 3N force were reversed, the resultantwould be √19. N. The value of P is

The direction of three forces 1 N, 2 N and 3 N acting at a point are parallel to the sides of an equilateral triangle taken in order. The magnitude of their resultant is

Three forces of magnitude 30, 60 and P acting at a point are in equilibrium. If the angle between the first two is 60°, the value of P is

A horizontal force F is applied to a small object P of mass m on a smooth plane inclined to the horizon at an angle θ. If F is just enough to keep P in equilibrium, then F =

The resultant R of two forces P and Q act at right angles to P. Then the angle between the forces is

The sum of the two forces is 18 and their resultant perpendicular to the lesser of the forces is 12, then thelesser force is

If the resultant of two forces is of magnitude P and equal to one of them and perpendicular to it, then the other force is
