Question

Electrostatic force is the force exerted by ______.

Options

• an electron on a neutron 

• one charge on another when the two are accelerating in a given frame of reference

• one charge on another when the two are moving in a given frame of reference

• one charge on another when the two are at rest in a given frame of reference

Answer 1

Electrostatic force is the force exerted by one charge on another when the two are at rest in a given frame of reference.

Explanation:

electrostatics refers to charges at rest or relatively at rest, this force can only be applied when charges form a steady electric field, which is only achievable when charges are at rest or nearly at rest.
