A) A point charge qq 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 = 2.00 nC and R = 0.100 m. B) if q = -3.00 nC and R = 0.100 m. C) if q= -3.00 nC and R = 0.200 m.
