(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?

Physics 2140 Electric Charge and Force Homework Name:
Physics 2140 Electric Charge and Force Homework Name:A thin semicircular rod like the one in problem 3 is broken into two halves. The top half has a total charge +Q uniformly distributed along it, and the bottom half has a total charge-Q uniformly distributed along it. On the diagram, indicate the direction of the net electric force on a positive test charge placed in turn at points A, B, and C. Explain how you determined your answers.

Question 3
what happens when a charged Insulator is placed near an uncharged metallic object? They repel each other. They attract each other. They exert no electrostatic force on each other. The charged Insulator always spontaneously discharges. They may attract or repel each other, depending on whether the charge on the insulator is positive or negative. 3. -11 points Three charges are arranged as shown in the figure below. Find the magnitude and direction of the electrostatic force on the...

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...
