If it were possible to remove gravity and friction, think about what would happen to a football if it were tossed into the air. Which statement best describes the force(s) acting on the football?
O A force must be applied to it when it slows to a position of rest.
O A force must be applied to it before it slows to a position of rest.
O No force is needed, an object in motion stays in motion.
Many forces must act upon it to keep it in motion.

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
