(a) A positive point charge Q is placed at the center of a cube.Draw the field lines for this charge configuration. Include atleast 7 field lines and be sure to show them passing through thesurface of the cube.
(b) What is the flux through one side of this cube? Hint: Do notunder any circumstances integrate to find the flux. Think about howmany sides the cube has and whether or not the flux through eachface is equal.
(c) If another positive point charge Q is placed outside one ofthe sides of the cube, how would the flux through that one side ofthe cube change? How would the flux through the entire cubechange?
