1. What is the repulsive force between two point charges that are 8.00 cm apart and have
equal charges of –30.0 nC?
2. Two point charges exert a 5.00 N force on each other. What will the force become if the
distance between them is increased by a factor of three?
3. Two point charges are brought closer together, increasing the force between them by a
factor of 25. By what factor was their separation decreased?
4. A test charge of +2 μC is placed halfway between a charge of +6 μC and another of
+4 μC separated by 10 cm. (a) What is the magnitude of the force on the test charge?
5. Two charges 10μC are placed 5.0mm apart.Determine the electric field at a point P on the
axis of the dipole 15 cm away from its centre O on the side of the positive charge.
6. Calculate the electric dipole moment for the following charge configuration.
