Question

A body acting upon 3 forces under equilibrium f1 10 N f2 6 N then f3

Answer 1

if their is equilibrium then we can say that the forces are balanced and the net force acting on a body is 0

Thus ,
F1 + F2 = F3
So,
10 + 6 = F3
Therefore,
F3 = 16

Hence, The 3rd force has a magnitude of 16 N
