2.1. Four 10nC positive charges are located in the z = 0 plane at the corners of a square 8cm on a side.A fifth 10nC positive charge is located at a point 8cm distant from the other charges. Calculate themagnitude of the total force on this fifth charge for e = €0:Arrange the charges in the xy plane at locations (4,4), (4,-4), (-4.4), and (-4,-4). Then the fifth chargewill be on the z axis at location z = 4/2, which puts it at 8cm distance from the other four. Bysymmetry, the force on the fifth charge will be z-directed, and will be four times the z component offorce produced by each of the four other charges.

Solution: 2.1 The charge configuration is shown in the figure below:

The classic Millikan oil drop experiment was the first to obtain an accurate measurement of the charge on an electron. In it, oil drops were suspended against the gravitational force by a vertical electric field. 1a. Given the oil drop to be 0.99 μm in radius and have a density of 910 kg/m3: Find the weight of the drop. 1b.If the drop has a single excess electron, find the electric field strength needed to balance its weight.
