How much work is required to bring three protons, initiallyinfinitely far apart,

Question

How much work is required to bring three protons, initiallyinfinitely far apart, to a configuration where each proton is1.5*10^-15m.
from the other two? (This is a typical separation for protons in anucleus.)

I tried working on this problem but I am stuck. I know that firstcharge is going to be 0 potential so no other charges re nearby.and the second charge is going to have a force from charge 3. andcharge 3 is going to have force from both 1 and 2. but I dont knowhow to incorparte in a formula.
we are given the d, we know the mass of proton. but still dont knowhow to solve it.

:Please any help is appreciated!

Explanation / Answer

given distance of each proton = d = 1.5*10-15m where q1= q2 = q3 = q =charge ofproton = 1.6*10-19C then work done = W = 3kq1q2/d where k= 9*109 plug in values W = -------J
