20.1 Electric Charge and Static Electricity
... The effect an electric charge has on other charges in the space around it is the charge’s electric field. • An electric field exerts forces on any charged object placed in the field. The force depends on the net charge on the object and on the strength and direction of the field at the object’s posi ...
