A cube and a sphere#

Part 1#

Compare the electric flux through the surface of a cube of side length \(a\) that has a charge \(q\) at its centre to the flux through a spherical surface of radius \(a\) with a charge \(q\) at its centre.

Answer Section#

  • The sphere has greater electric flux passing through it.

  • The cube has greater electric flux passing through it.

  • The same electric flux passes through each surface.
