repulsion. This force,applied by a magnet,is
the magnetic force.

10.  A plastic pen when rubbed on hair can
attract small pieces of paper.This is due to
electrostatic force.

force between them.This attractive force is
the gravitational force.

known as mechanical force.

13.  When an object moves over another
object,the force which opposes the relative
motion of the objects is the frictional force.
