(Electric force on charged particle) An electron is initially at rest right at the mid-point between two parallel charged plates. Suppose the separation of the plates is 5cm, and the uniform electron field between them has a strength of magnitude 100 N/C. Ignore the effect of gravitation and the edge effect of parallel plate electric field. Given that the mass of an electron is 9.11 × 10-31 kg. (a) Draw the electric field lines and state towards which plate will the electron move. (b) Calculate the electric force acting on the electron. (c) Calculate the time duration until the electron reaches one of the plates.

Sketch the electric field lines in the vicinity of the conductor in Figure 18.49 given the field was originally uniform and parallel to the object's long axis. Is the resulting field small near the long side of the object?
Nobel laureate Richard Feynman (19181088) once said that if two persons stood at arms length from each other and each person had 1% more electrons than protons, the force of repulsion between them would be enough to lift a weight equal to that of the entire Earth. Carry out an order-of-magnitude calculation to substantiate this assertion.

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.
