The greatest and least resultant of two forces acting at a point are 16N and 4N. If they are acting at an angle 120 degrees with one another their resultant is A. root 38N , B.root 76N, C.root 19N, D.none

The magnitude of two vectors p and q differ by 1. The magnitude of their resultant makes an angle of tan inverse ( 3 / 4 ) with p. The angle between p and q is

Which of the following sets of forces acting simultaneously on a particle keep it in equilibrium?

The vectors sum of two vectors of magnitude 10units and 15units can never be

if theta is the angle between unit vectors A bar and B bar, then (1-A bar.B bar)/(1 plus A bar.B bar) is equal to

4 factorial * 5c2 * 6 = 1440
