- 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 gravity by a vertical electric field. microscope Assume the oil drop to be 1.90 µm in radius and have a density of 922 kg/m3. (a) Find the weight of the drop. N (b) If the drop has a single excess electron, find the magnitude of the electric field strength needed to balance its weight. N/CImagine two concentric spherical conductive shells of radii 5 cm and 10 cm. Originally the inner sphere is charges with 2 µC and the outer with -1 µC. Then they are connected with a conductive wire. After the charge exchange has taken place, what are the charges on each of the shells? 91= μC, 92= μC.A circular plastic disk with radius R = 2.00 cm has a uniformly distributed charge Q = +(2.00 x 106)e on one face. A circular ring of width 30 µm is centered on that face, with the center of that width at radius r = 0.50 cm. In coulombs, what charge is contained within the width of the ring?
- A point charge, q = -5.0 nC, and m = 2.0 x 10-18 kg, is shot vertically upward with an initial speed of 3.0 x 105 m/s from a thin, infinite, planar sheet of uniform charge with surface charge density of σ = +4.0 nC/m^2 . To what vertical elevation will q rise above the sheet of charge? Neglect gravityA particle of mass 5.4×10^−6 g and a charge of −2 nC starts out traveling horizontallyat 500 m/s straight between two oppositely charged plates separated by 3 cm. The plateshave surface charge densities of 9 µC/m^2Determine the following:a) How long till it impacts either plate?b) How far will it travel horizontally until it impacts one of the plates?Suppose a speck of dust in an electrostatic precipitator has 8.0000 × 10+" protons in it and has a net charge of 2.00 nC (a very large charge fọr a small speck). How many electrons does the speck have? Include 5 significant figures in your answer. For this problem, use e = 1.6022 × 10¬1º C as the fundamental charge. n = number (5 significant figures)
