Two small spheres spaced 20.0 cm apart have equal charge.How many excess electrons must be present on each sphere if the magnitude of the force of repulsion between them is 4.57 × 10-21 N? Number of Electrons = ?

♦ Relevant knowledge
An electrostatic force within the physics field can be described as the repulsive, or attractive force that occurs between two different or similar types of charges. The electrostatic force in turn varies according to the square of charge. The unit of measurement is Newton.
