Calculate Repulsive Force of 2 Protons in Atom

[lilkrazyrae]

Find the repulsive force on two protons in the nucleus of an atom assuming they are separated by the minimum distance of 1.00 x 10^-15m.

So F=k lq(1)l^2/ r^2
=8.99 x 10^9 (1.602 x 10 ^-19)^2/(1.00 x 10^15m)
=230.7N

Is this correct?

Is this correct?

Answer looks right to me, though you made several mistakes in writing out the formula.
