Two concentric cubical surfaces enclosing a central point charge.
Two concentric cubical surfaces enclosing a central point charge.
A point charge of magnitude \(q\) is located at the center of a closed, cubical Gaussian surface with side length \(L\). The side length of the cube is then doubled to \(2L\) while keeping the point charge centered inside. What is the ratio of the new total electric flux through the cube to the original total electric flux through the cube?
