what is deforming force & restoring force?
@Ruhi,
You can refer to the answer posted by your friend, thanks.
Also...
Deforming force can also be termed as the force which displaces a body from its original position or configuration by either changing its location or its shape.
Restoring force tends to move the place the body back to its original position or configuration.
