Homework Statement
An electron is separated from a potassium nucleus (charge 19e) by a distance of 5.2 X 10-10m. what is the electric force between these particles? (e = 1.60 X 10-19C, Kc= 8.99 X 109 N*m2/C2)
Homework Equations
Felectric= Kc[(q1)(q2)/r2]
The Attempt at a Solution
Felectric= 8.99 X 109[(19e)(-1.6 X 10-19)/(5.2 X 10-10)2]
Felectric= -1.62 X 10-8
Is this correct?
