Which of the following is an example of a non-contact force?
-
The force exerted by magnets
-
The force exerted by us to lift a bucket
-
Push a stationary car
-
Force due to friction
That's Correct!
It's Wrong!
The force exerted by magnets is an example of a non-contact force because it can act on objects without physically touching them. Magnets have a magnetic field that can attract or repel other magnetic objects from a distance. This force can be observed when two magnets are brought near each other and they either attract or repel each other without any direct contact. Therefore, the force exerted by magnets is a non-contact force.
