# Question

A Gaussian surface has sixteen field lines leaving it when it surrounds a point charge of + 10.0μC and seventy-five field lines entering it when it surrounds an unknown point charge.

(a) The magnitude of the unknown charge is (1) greater than 10.0μC, (2) equal to 10.0 μC, (3) less than 10.0 μC. Why?

(b) What is the unknown charge?
