Two point charges q = 21.0 nc and q = 21.0 nc are in vacuum located on the x axis at 21.0 cm and 21.0 cm, respectively. choosing the normal to the plane in the positive x direction, calculate the total electric flux through the yz plane.
two point charges with the same charge and the same position? the electric flux through the yz plane is equal to exactly half of the flux (Gaussian surface!) through a sphere encapsulating the "two" point charges in the question.
