A small electrically charged aluminum sphere (mass 20.0 ?, charge −5.00 ??) is placed on a plastic tabletop. Your goal is to set up an electric field that will result in the sphere accelerating upwards at 13.0 ?⁄?^2 over a distance of 1.00 ?.
a) Draw a force diagram for the sphere while it is in motion.
b) Determine the magnitude and direction of the E-field required to make the sphere move in this particular way.
c) What assumptions did you make in part b.?

A small electrically charged bead with the mass m and charge Q can slide on a circular insulating string without friction. The radius of the circle is r. A point-like electric dipole is at the center of the circle with the dipole moment P lying in the plane of the circle. Initially the bead is at an angle θ = 플 +6, where δ is infinitely small, as shown schematically in the figure below. Figure 3: Bead on a string...
