    Electrostatics charged spheres problem

    1)Two small equally charged spheres, each of mass m, are suspended from the same point by silk threads of length l.The distance between the spheres x<<l.Find the rate dq/dt with which the charge leaks off each sphere if their approach velocity varies as v=a/(x)^0.5, a is a constant...

    A question of charged spheres and voltages

    I have a question regarding charged spheres and voltage measurements. I've talked to my physics professor about it, and he wasn't quite sure of the answer (although to be fair, I asked briefly at the end of class.) Imagine that you had a spherical shell, charged to a high potential (for the...

    How Do You Calculate the Charge on the Inner Sphere Using Gauss's Law?

    Two charged concentric metal spheres have radii of 3.000 cm and 3.500 cm. Calculate the charge in nC on the inner sphere if the radial electric field at a radial distance 3.125 cm is 7.366e+04 N/C. I tried using Gausses law of EA = Q/e0 then after getting Q I would take the average charge...
