Assume that a ball of charged particles has a uniformly distributed negative charge densityexcept for a narrow radial tunnel through its center, from the surface on one side to thesurface on the opposite side. Also assume that we can position a proton anywhere along thetunnel or outside the ball. Let FR be the magnitude of the electrostatic force on the protonwhen it is located at the ball's surface, at radius R. As a multiple of R, how far from the surfaceis there a point where the force magnitude is 0.52FR if we move the proton (a) away from theball and (b) into the tunnel?(a) Number i(b) NumberiUnitsUnits

Two spherical cavities, of radii a and b, are hollowed out from the interior of a (neutral) conducting sphere of radius R (see attatched image). At the center of each cavity a point charge is placed. Call these charges qa and qb. What is the field outside the conductor and what is the field within each cavity?

A ring and a disk both are centered at (0, 6, 3) and are both lying on the plane y = 6. The ring has a radius of 7 m, while the disk has a radius of 9 m, so that the ring is around the disk. Determine the magnitude of the electric field in kV/m at point (0, -9, 3) if the ring has a total charge of -8 mC and the disk has a total charge of 6 mC. All coordinates are measured in meters.
A proton is held stationary at distance d, from an infinitely large conducting plane (sheet) of charge with uniform charge density -o. It is then released and moves straight towards the plane. Find the speed of the proton when it is at distance d, from the plane. The electric field of the plane is uniform everywhere in space and has the magnitude E = Ignore the gravitational force. Present your answer symbolically.
Suppose you design an apparatus in which a uniformly charged disk of radius R is to produce an electric field. The field magnitude is most important along the central perpendicular axis of the disk, at a point P at distance 2.60R from the disk (see Figure (a)). Cost analysis suggests that you switch to a ring of the same outer radius R but with inner radius R/2.60 (see Figure (b)). Assume that the ring will have the same surface charge density as the original disk. If you switch to the ring, by what part will you decrease the electric field magnitude at P?

In the figure a smallI, nonconducting ball of mass m = 0.92 mg and charge q = 2.0 x 108 C (distributed uniformly through its volume) hangs from an insulating thread that makes an angle 0 = 39° with a vertical, uniformly charged nonconducting sheet (shown in cross section).
