Question

At what angle must the two forces of 50 and 120 Newtons be acting, so as to
be balanced by a force of 130 Newtons.

Answer 1

The angle must be 90°

because the two force acting (50,120) are perpendicular to eachother thus resultant given by R = √ A*2+ B*2 ( general formula ) when angle b/w two vector = 90°
