A particle ,O, of mass U , travelling with a velocity of 3,0×10^7m/s collides elastically with another particle ,P, of mass 16U ,initially at rest . after collision particle O moves in a direction of 90° from its original path Using revolution of vectors and the principle of conservation of momentum ,Calculate the speed of P after collision​

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
