The electric field, force of interaction and work done

1 The electric field, force of interaction and work done 

Any effect which an ion possesses by virtue of its charge must be susceptible to exp eri-mental measurement, and this cannot be done for an ion in isolation. For the present discussion, a second charge or ion is introduced so that the effect of the first charge on the 

A second charge or ion placed at some distance, r, from the first charge, or ion, results in an electrostatic interaction where the force between the two charges depends on  

One of Coulomb s experiments involved bringing one charged sphere up to another charged sphere. This experiment can be used to discuss electrostatic forces and work done on systems where electrostatic interactions are involved. 

The work done by a force = the magnitude of the force x the displacement in the direction of the force
