An aeroplane flies in a loop (a circular path in a vertical plane) of radius 200 m. the pilot's head always points toward the centre of the loop. the speed of the aeroplane is not constant; the aeroplane goes slowest at the top of the loop and fastest at the bottom. at the top of the loop, the pilot feels weightless. what is the speed of the aeroplane at this point?
at the bottom of the loop, the speed of the aeroplane is 280 km/h . what is the apparent weight of the pilot at this point? his true weight is 710 n .

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
