Answer to Question #126169 in Electricity and Magnetism for SOLOMON GOMASHIE

Question

Two positive charges of equal magnitude 10 nC are separated by a distance of 10 em. What is the
total force due to these two charges on a 0.5 nC test charge placed midway between them?

Answer 1

Two positive charges of equal magnitude create the equal forces in the opposite directions, for the force magnitude depends only on the charge magnitude and distance from the charge to the point, according to the Coulomb's law.

Thus, the net force due to these two charges on a test charge placed midway between them will be equal to zero.

Answer. 0 N.
