A charge of +Q attracts a charge of -Q 1 cm away with a force of F. Another charge of +Q is placed next to the first one. The force on the charge of -Q is now

Question

Quizplus · Accepted Answer

The force between two charges is given by Coulomb's law, which states that the force is proportional to the product of the charges and inversely proportional to the square of the distance between them. When another charge of +Q is placed next to the first one, the force on the charge of -Q doubles because the force from each +Q charge adds up, resulting in a total force of 2F.
