The resultant of two forces acting at a point at an angle 120 degrees is perpendicular to the smaller one. If the smaller force is 7N, find the greater force.

See let's say the small for in X direction so the large force will make 120 degrees from that thus 30 degrees from y axis. X component of this force should be equal to 7

Fsin30=7
F=14
