A total charge Q is distributed uniformly throughout a spherical volume that is centered at 01 and has aradius R. Without disturbing the charge remaining, charge is removed from the spherical volume that iscentered at O2, as shown in the figure. Show that the electric field everywhere in the empty region is given bywhere r is the displacement vector directed from O1 to 02.4TE,R3'(Hint: Model the sphere as a positively charged sphere with no cavity + negatively charged sphere withnegative charge at the location of the cavity. Then pick a point inside the negatively charged sphere (not at itscenter, since you need to prove the expression is correct for anywhere inside the cavity) and use gauss's lawto find the electric field due to each sphere).02R
