Two blocks are stacked on top of each other on the floor. the friction coefficient is 0.2 between all contacting surfaces. take this to be both the static and kinetic coefficient of friction. then the horizontal 10n force is applied to the lower block. what is the horizontal component of the force exerted by the floor on the lower block?

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
