How is the electrostatic force affected when the magnitude of a charge is doubled? the magnitude of the electrostatic force doubles the magnitude of the electrostatic force will decrease by one half. the magnitude of the electrostatic force will be quadrupled. the magnitude of the electrostatic force will be reduced to 1/4 of the original magnitude.

The magnitude of the electrostatic force between two charges is given by:

where
ke is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the two charges

We can see that the magnitude of the force is directly proportional to the charges. This means that when one of the charges is doubled, the magnitude of the electrostatic force will double as well, so the correct answer is
A) The magnitude of the electrostatic force doubles
