Apoint charge with charge q1 = 3.10 μc is held stationary at the origin. a second point charge with charge q2 = -4.50 μc moves from the point ( 0.140 m , 0) to the point ( 0.265 m , 0.265 m ). how much work w is done by the electric force on the moving point charge?

W = 0.562 J

Explanation:

Initial potential energy of two point charges is given as

here we have

now we have

now at final position the distance between two charges is given as

Now final energy is given as

Now the work done to change the position of charge is given as

mistakes are ok
