A 3.5-C point charge sits in the center of a cube and the electric flux through one of the cube's sides is 6.6 * 10¹⁰ Nm²/C .What is the length of one of the edges of the cube?

Question

Quizplus · Accepted Answer

The electric flux through a closed surface is given by Gauss's Law, which states that the total electric flux through a closed surface is equal to the charge enclosed by the surface divided by the permittivity of free space ($\epsilon_0$). Since the flux given is through one side of the cube, and the charge is symmetrically placed at the center, the total flux through the cube would be the same through each side due to symmetry. However, the length of the cube's edges cannot be determined from the electric flux alone because the flux depends on the charge inside and the permittivity of free space, not the size of the cube.
