2) Two electrons in an atom are separated by 1.6 x 10 ^-10 m, the typical size of an atom. The coulomb constant is 9 x 10^9 N *m^2/C^2. What is the force between them? Answer in units of N.

I tried using coloumbs law but not sure

Use coulombs law

F = q1*q2/(4*pi*r^2) = (1.6e-19)^2*9*10^9/(1.6*10^-10)^2

F = 9*10^-38*10^9/10^-20 = 9*10^-9 Nts
