At time =0, a proton is at rest at location <4.7, 1.8, 0>x 10^-6m. An electron is at <2.9,8.7,0> x 10^-6 m. and ismoving with a momentum of <3.6,-7.8,0> x 10^-27 kg*m/s. theproton and electron are in outer space, far from any other matter.The proton has a charge of 1.6 x 10^-19 C, and the elctrons chargeis exactly the negative of this value.
A.) what is the magnitude of the gravitational force on theelectron by the proton?
B.) what is the magnitude of the electric force on the electronby the proton. By what factor is it larger than the gravitationalforce?
C.) what is the electric force vector on the electron by theproton?
D.) after time 2.0 x 10^-10 s, what is the momentum of theelectron?
