An election enters a region between two large parallel plates made of aluminum separated by a distance of 2.0 cm and kept at a potential difference of 200 V.

In the early 1900's Robert Millikan discovered the peculiar property that charge came in little packets, no smaller than e = 1.602 x 10-19 C -- he had measured the charge of the electron. Here's (roughly) how he did it. He removed an electron from an initially neutral droplet of oil with diameter 0.5 ??μm. In a vacuum, he positioned the droplet between two metallic plates separated by 6 mm and fiddled with the potential (voltage) across the plates until the droplet would hover against the force of gravity. Droplets of this size with +e charge would hover, but only for a particular voltage (otherwise they would sink or rise). Given the parameters stated here, and the fact that the density of the oil was 831 kg/m3, what was the voltage that made the droplets hover? (give your answer with 0.1 V precision)
The electric potential at large distances from the dipole (i.e. ligand >> d) is described by the relationship V (r, α) = kQ? ∙ cosα?2, where d is the distance between the charges of the dipole and r is the distance from the dipole center. In the Cartesian system whose beginning is halfway between the charges of the dipole, and the axis of the dipole is the X axis (see figure), and limited to the two-dimensional case, the given relationship is as follows:V (x, y) = k ∙ Q? ∙ x / (x2 + y2) 3/2Using this relationship, determine the coordinates of the electric field intensity vector at the point with the coordinates P = (R, R), i.e. at any point lying on the straight line lying at the angle α = π / 4 at a distance of √2 ∙ R from the origin of the coordinate system, at a large distance from the origin coordinate system.
