Question

A free electron and a free proton are exactly 1.0 com apart. Find the magnitude and direction of (a) the acceleration of the proton and (b) the acceleration of the electron.

Answers

How far is a com? Do you mean centimeter (cm) ?)

Use Coulomb's Law for the force, F.

F = ke^2/d^2

For the acceleration a, use

a = F/m

m = electron mass

yeah I meant cm. so for F= 8.99*10^9(9.11*10^-31)/ .01m^2 ?

NO. Instead of the square of the elctron charge, e^2, in units of coulomb^2, you have used the electron mass,in kg.
