Physics Electrostatics Level: Misc Level

A point charge + Q is located on the x -axis at x = a, and a second point charge - Q is located on the x - axis at x = - a. A Gaussian spherical surface with radius r = 2 a is centered at the origin. The flux through this Gaussian surface is

a. zero because the net charge enclosed by the Gaussian surface is zero

b. greater then zero

c. zero because at every point on the surface the electric field has no component perpendicular to the surface

d.zero because the electric field is zero at every point on the surface

e.none of the above
