Find the magnitude of the acceleration of the electron.
Express your answer with the appropriate units.

Find the direction of the acceleration of the electron.

Answer 1

The electron will accelerate toward the proton (opposite charges attract)

F = k Qe^2/(.007)^2

where Qe is electron charge and proton the same but plus

a of electron = F/Melectron
a of proton = F/Mproton
