A charge Q is placed at a distance `a/2` above the centre of a horizontal, spuare surface of edge a as shown in figure (30-E1). Find the flux of the electric field through the square surface.

a. Any line emitting from charge q to the right of line AB will
pass through the infinite plane. It means half flux will pass
through the plane. So the flux passing through the plane is
`q//2epsilon_0`.

q is above the centre at a small distance. So this
becomes similar to the case (a).
