(a) Draw a microscopic representation of what happens to the charge distribution in a dielectric placed in an external uniform electric field. For simplicity, make the dielectric of some regular shape. How can you test your explanation? (b) What happens if you cut the dielectric in half (in the direction perpendicular to the direction of the E field), separating the halves by a small gap, while keeping it in the external field? How could you test your answer?
please draw the diagrams for the question

A negatively charged oil drop whose mass is 10-15 kg and
whose charge is -6.4 10-19 Coulombs remains stationary under the
influence of the Earth’s gravitational field and a uniform external
electric field made by two oppositely-charged parallel plates (see
diagram below). Ignore the influence of Earth’s electric field on
the oil drop.
Determine the magnitude and direction of the net
electric field created by the plates (not the electric field of the
oil drop !). Explain completely how you...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
