I'm sure this is so easy and just 1 step. I can do questions like this, I just don't understand, this theory one, or whatever it is.
How far apart are two protons if they repel each other with a force of 1.0 mN?
F=k * Q1Q2/r^2
k=9.00*10^9
e=1.6*10^-19
F=k * Q1Q2/r^2
.001N = 9*10^9 * 1.6*10^-19 * 1.6*10^-19/ r^2
.001 = 2.304 *10^28/r^2
r^2= 2.304*10^28/.001
r= 4.8 * 10^-13 m.***the answer key says: 1.5 x 10-11 m.
please if you could help me quick it would be amazing.

The Attempt at a Solution
F=k * Q1Q2/r^2
.001N = 9*10^9 * 1.6*10^-19 * 1.6*10^-19/ r^2
.001 = 2.304 *10^28/r^2
r^2= 2.304*10^28/.001
r= 4.8 * 10^-13 m.***the answer key says: 1.5 x 10-11 m.
