Aparticle with a charge of +10 μc is moving at 390 m/s in the positive z-direction. (a) find the minimum magnetic field required to keep it moving in a straight line at constant speed if there is a uniform electric field of magnitude 125 v/m pointing in the positive y-direction. (b) find the minimum magnetic field required to keep the particle moving in a straight line at constant speed if there is a uniform electric field of magnitude 125 v/m pointing in the positive z-direction. explain (show all work) for each answer.

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
