A standard clock of radius R has an electrical short that charges up the black metal rim of thickness L with a uniform surface charge density o produces a potential V at point above the center of the disk at point P, as shown. Determine the electric field vector at point P, which is a distance d above the center of the clock.

Review. From a large distance away, a particle of mass m1, and positive charge q1 is fired at speed in the positive x direction straight toward a second particle, originally stationary but free to move, with mass m2, and positive charge q2. Both particles are constrained to move only along the x axis. (a) At the instant of closest approach, both particles will be moving at the same velocity. Find this velocity, (b) Find the distance of closest approach. After the interaction, the particles will move far apart again. At this time, find the velocity of (c) the particle of mass m1, and (d) the particle of mass m2.

The dome of a Van de Graaff generator receives a charge of 2.0 104 C. Find the strength of the electric field (a) inside the dome, (b) at the surface of the dome, assuming it has a radius of 1.0 m, and (c) 4.0 in front the center of the dome. Hint: See Section 15.5 to review properties of conductors in electrostatic equilibrium. Also, note that the points on the surface are outside a spherically symmetric charge distribution; the total charge may be considered to be located at the center of the sphere.
A particle of charge +q and mass m moves with velocity v0 pointed In the +y-direction as It crosses the x-axis at x= R at a particular time. There is a negative charge -Q fixed at the origin, and there exists a uniform magnetic field B0 pointed in the +z-direction. It is found that the particle describes a circle of radius R about -Q. Find B0 in terms of the given quantities.

The electric field along the axis of a uniformly charged disk of radius R and total charge Q was calculated in Example 23.3. Show that the electric field at distances x that are large compared with R approaches that of a particle with charge Q = R2. Suggestion: First show that x/(x2 + R2)1/2 = (1 + R2/x2)1/2 and use the binomial expansion (1 + )n = 1 + n, when 1.
