Question

The sum of two forces acting at a point is 8N. If the resultant force is 4N and its direction is perpendicular to minimum force then the forces are:
a) 2N and ON b) 3N and 5N c) 4N and 4N d) None of these

and please explain what is meant by sum of two forces acting at a point?? please!!​

Answer 1

sum of 2 force acting at a pt. mean that the magnitude of addition of 2 forces is 8N

I.e F1 + F2 = 8N
