Two forces P and Q acting at a point are such that if P is reveserd, the direction of the resultant is turned through `90^(@)`. Prove that the magnitudes of the forces are equal.

Two forces act at a point and are such that if the direction of one is reversed, the resultant is turned through a right angle. Show that the two forces must be equal in magnitude.

Two forces P and 2P act at a point. If the first force is increased by 5N and the other trebled, the direction of the resultant is not altered then find 'P'

Two forces vec(P) and vec(Q) are acting at a point. If vec(P) is reversed, the new resultant becomes perpendicular to the initial resultant. Then:

The sum of the magnitudes of two forces acting at a point is 18 and the magnitude of their resultant is 12. If the resultant is at 90^(@) with the force of smaller magnitude, What are the magnitudes of forces?
