This force can either push the block upward at a constant velocity or allow it to slide downward at a constant velocity. the magnitude of the force is different in the two cases, while the directional angle θ is the same. kinetic friction exists between the block and the wall, and the coefficient of kinetic friction is 0.310. the weight of the block is 55.0 n, and the directional angle for the force is θ = 50.0°. determine the magnitude of when the block slides (a) up the wall and (b) down the wall.

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
