Two vectors of magnitudes 5 and 3 give a resultant of magnitude 2. What must be the angle between the two vectors ?

Two forces of magnitude 1 N and 13 N resultant of magnitude 6sqrt(5)N, then that is the angle between two forces.

A vector of magnitude a is turned through angle theta . The magnitude of change in the vector is given by:

If two forces are acting at a point such that the magnitude of each force is 2 N and the magnitude of their resultant is also 2 N, then the angle between the two forces is

Two vectors, equal in magnitude, have their resultant equal in magnitude of the either. The angle between the two vectors is _____.
