← A student finds the total force on a test charge from two charges. The two forces have sizes 9 N and 12 N and are perpendicular. She gives the answer 21 N. Which correction is right?Two charges in air exert a force of 12 N on each other. They are put in a liquid, at half of the old distance, and now the force is 8 N. What is the dielectric constant of the liquid? →
