Two spherical cavities, of radii a and b, are hollowed out from the interior of a (neutral)

Question:

Two spherical cavities, of radii a and b, are hollowed out from the interior of a (neutral) conducting sphere of radius R (Fig. 2.49). At the center of each cavity a point charge is placed???call these charges q_a and q_b.?

(a) Find the surface charges ?_a, ?_b, and ?_R.?

(b) What is the field outside the conductor??

(d) What is the force on q_a and q_b??

(e) Which of these answers would change if a third charge, q_c, were brought near the conductor?
