Apoint charge with charge q1 = 4.00 μc is held stationary at the origin. a second point charge with charge q2 = -4.40 μc moves from the point ( 0.155 m , 0) to the point ( 0.245 m , 0.270 m ). how much work w is done by the electric force on the moving point charge?

W=0.94J

Explanation:

Electrostatic potential energy is the energy that results from the position of a charge in an electric field. Therefore, the work done to move a charge from point 1 to point 2 will be the change in electrostatic potential energy between point 1 and point 2.

This energy is given by:

So, the work done to move the chargue is:

The work is positive since the potential energy in 1 is greater than 2.
