Question

What’s the equalibrium rule?

Answer 1

The 50 N force is not equal to the 30 N force. If an object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describeequilibrium situations. Thus, the net force is zero and the acceleration is 0 m/s/s.

Answer 2

The vector sum of forces acting on a non-accelerating object equals zero.
equation form: ΣF = 0
