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

The square of the resultant of two forces 4N and 3 N exceeds the square of the resultant of the two forces by 12 when they are mutually perpendicular. The angle between the vectors is

Two forces, each of magnitude F have a resultant of the same magnitude F. The angle between the two forces is

Two forces, each of magnitude F have a resultant of the same magnitude F. The angle between the two forces is

Two forces with equal magnitudes F act on a body and the magnitude of the resultant force is F /3. The angle between the two forces is

Two force F_(1)" and "F_(2) are acting on a body. One force is double that of the other force and the resultant is equal to the greater force. Then the angle between the two forces is :-

Two forces F_(1) and F_(2) are acting on a body. One force is double that of the other force and the resultant is equal to the greater force. Then the angle between the two forces is

The resultant of two forces 3P and 2P is R. If the first force is doubled then resultant is also doubled.The angle between the two forces is

The resultant of two forces 3P and 2P is R. If the first force is doubled then resultant is also doubled.The angle between the two forces is

The resultant of two forces 2 N and 3 N is sqrt(19) N. The angle between the forces is

Two forces of magnitude 8 N and 15 N respectively act at a point . If the resultant force is 17 N , the angle between the forces has to be
