Question

forces act at angle of 120°. The higher force is of 40N and the resultant is perpendicular to the smaller one. find the smaller force.​

Answer 1

Answer:

Now, the resultant force makes an angle 90° with the smaller force. So, angle between resultant force and the larger force = (120° - 90°) = 30°. F = 20. So, magnitude of smaller force is 20 Newtons.
