Acapacitor is made from two hollow, coaxial, iron cylinders, one inside the other. the inner cylinder is negatively charged and the outer is positively charged; the magnitude of the charge on each is 12.0 pc . the inner cylinder has a radius of 0.600 mm , the outer one has a radius of 7.00 mm , and the length of each cylinder is 12.0 cm . (a) what is the capacitance? (b) what applied potential difference is necessary to produce these charges on the cylinders?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
