When a cube is inscribed in a sphere of radius r, the length L of a side of the cube is sqrt(4/3)*r . If a positive point charge Q is placed at the centre of the spherical surface, the ratio of the electric flux sphere at the spherical surface to the flux cube at the surface of the cube is? Explain please I know how to find the flux of a sphere how would I find it for a cube? Then would I put sphere over cube to solve the question?
