Acharged sphere with 1 × 10 8 units of negative charge is brought near a neutral metal rod. the half of the rod closer to the sphere has a surplus charge of 4 × 10 4 units. what is the charge on the half of the rod farther from the sphere? 0 − 1 × 10 8 1 × 10 8 − 4 × 10 4 4 × 10 4

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
