If the resultant of two forces of magnitudes `p` and `2p` is perpendicular to `p`, then the angle between the forces is

Two forces P and Q have a resultant perpendicular to P. The angle between the forces is

Two forces of equal magnitude act simultaneously on a partical. If the resultant of the forces is equal to the magnitude of each of then the angle between the forces is

The resultant of two forces 1and P is perpendicular to l and equal to 1.What is the value of P and angle between the forces

The resultant of two forces, one double the other in magnitude is perpendicular to the smaller of the two forces. The angle between the two forces is
