The resultant of two forces 2P and sqrt(2)P is sqrt(10)P .The angle between the forces is

The resultant of two forces 2P and sqrt2P is sqrt10P .The angle between the forces is

At what angle should the two forces 2P and sqrt(2P) and Psqrt(2)P act so that resultant force is Psqrt(10) ?

If two numerical equal forces P and P acting at a point produce a resultant force of magnitude P itself, then the angle between the two original 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
