Asked by Kayla

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.
Answered by drwls
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

Answered by Kayla
yeah I meant cm. so for F= 8.99*10^9(9.11*10^-31)/ .01m^2 ?
Answered by drwls
NO. Instead of the square of the elctron charge, e^2, in units of coulomb^2, you have used the electron mass,in kg.
