Apoint charge q is at the point x = 0, y = 0, z = 0. an imaginary hemispherical surface is made by starting with a spherical surface of radius r centered on the point x = 0, y = 0, z = 0 and cutting off the half in the region z< 0. the normal to this surface points out of the hemisphere, away from its center. calculate the electric flux through the hemisphere if q = 7.00 nc and r = 0.100 m.
