Question

If the body is at rest while I am pushing it with a force of 20 Newtons and the force of static friction is 20 Newtons, will it move or should I push with a force greater than 20​

Answer 1

It will not move, so you should push with a force greater than 20 N.

Step-by-step explanation:

Static friction is a force that keeps a body at rest. This means static friction will be the force that keeps the body from moving when there is no push or pull hence you should overcome it with enough opposing force for the body to move.

In this case for the body to move , you should push with a force greater than 20 N for it to move.
