A charged belt, 55 cm wide, travels at 33 m/s between a source of charge and a sphere. The belt carries charge into the sphere at a rate corresponding to 87 µA. Compute the surface charge density on the belt.
An electron is fired at a speed vi = 3.1 × 106 m/s and at an angle θi = 36.8° between two parallel conducting plates as shown in the figure. If s = 1.8 mm and the voltage difference between the plates is ΔV = 98.8 V, determine how close, w, the electron will get to the bottom plate. Put your answer in meters and include at 6 decimal places in your answer. Do not include units. The x-axis of the coordinate system is in the middle of the parallel plate capacitor
We have the electric field: E = 5xx + 2y + (4/π)z. (a) Calculate its flow through the three surfaces S1, S2, S3 of the figure. The S3 measure is the fourth of the surface area of a unit radius and center that coincides with the beginning of the axes. (b) If there are no loads in the space, calculate the flow of E from the curvilinear surface. (ni, x, y, z are unit vectors)

Consider an infinitely long wire of charge carrying a positive charge density of A. The electric field due to λ this line of charge is given by E= 2kef= -, where is a unit vector directed radially outward Σπερμ from the infinitely long wire of charge. Hint #3 a. Letting the voltage be zero at some reference distance (V(ro) = 0), calculate the voltage due to this infinite line of charge at some distance r from the line of charge. Give your answer in terms of given quantities (A,ro,r) and physical constants (ke or Eo). Use underscore ("_") for subscripts and spell out Greek letters. Hint for V(r) calculation 3 V(r) = b. There is a reason we are not setting V(r → ∞o) = 0 as we normally do (in fact, in general, whenever you have an infinite charge distribution, this "universal reference" does not work; you need a localized charge distribution for this reference to work). Which of the following best describes what happens to potential as roo? (That is, what is V(ro), with our current…

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)
