I need the answer as soon as possible

Extracted text: Rotating Hollow Ball. There is a hollow sphere rotating about its axis with angular velocity, as in Figure 2. The total charge is Q and is evenly distributed over its surface. far radius of the ball is R. (a) Determine the electric field E- outside and inside! (b) Determine the potential of the vector A- outside and inside! (Hint: don't use rotation axis as a fixed axis, but use the axis of the intended position.) (c) Determine the magnetic field B~ outside and inside! (d) Determine the total energy of the system! R
