A positive charge Q is located at the center of an imaginary Gaussian cube of sides a. The flux of the electric field through the surface of the cube is Φ. A second, negative charge -Q is placed next to Q inside the cube. Which of the following statements will be true in this case?

According to Gauss's law, the net electric flux through a closed surface depends on the net charge enclosed. Since the charges +Q and -Q cancel each other out, the net charge inside the cube is zero, resulting in zero net flux.
