Here you can find the meaning of A charge q is located at the centre of a cube. This result shows that the electric flux through any face of the cube is proportional to the charge q, and does not depend on the size of the cube or the distance from the charge to each face. Where ε0 is the permittivity of free space. Since k is a constant, we can simplify this expression to: Therefore, the electric flux through any face of the cube is 4kq. Substituting this expression for E into the equation for electric flux, we get: Since the charge is located at the center of the cube, the distance from the charge to each face of the cube is half the length of one side of the cube (i.e. To find the electric field, we can use Coulomb's law, which states that the magnitude of the electric field due to a point charge q at a distance r from the charge is given by: The area of each face of the cube is the same, and is given by the formula A = s^2, where s is the length of one side of the cube. Therefore, the electric field has the same magnitude at every point on each face. Since the charge is located at the center of the cube, the electric field is radial and points directly towards each face of the cube. Where E is the electric field and A is the area of the face. The electric flux through any face of the cube is then given by: In this case, we can choose a cube as our closed surface, and since there is only one charge located at the center of the cube, the charge enclosed by the cube is q. Gauss's law states that the electric flux through a closed surface is proportional to the charge enclosed by that surface. We can use Gauss's law to find the electric flux through any face of the cube.
