Alex stands on the edge of shs building with a H=101.2m , dropping a tennis ball straight down horizontal , with a velocity of 25m/s on the horizontal ground , Arval is speeding up to catch the ball 4m/s trying to catch the ball. if lester stands 1.2 , and start at x meters away from the drop point , what does x need to be for him to successfully catching the ball?

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
