If the sum of all the forces acting on a body is zero, is it necessarily in equilibrium? If the sum of all the forces on a particle is zero, is it necessarily in equilibrium?
Answers
Answer ⇒ No, It the sum of all the forces acting on the body is zero then it not necessarily that the body will be in the state of the Equilibrium.
Explanation⇒ The sum of all the forces acting on the body is zero then it not necessarily that the body will be in the state of the Equilibrium. For the explanation let us take an example.
Let us assume that the two equal and opposite forces having their line of actions at a certain distance apart act on a body, then the body in this case will remain stationary at the point but will have not have the rotation due to the torque produced.
Also, we can say that If the sum of all the forces acting on a particle is zero then it is necessarily in equilibrium because there will not be a distance between anti-parallel forces.
