Explanation / Answer

I am assuming the traiangle formed by protons to be equilateral

1.

Electric field due to proton placed on x axis at origin is equal and opposite hence they cancel each other, now the net electric field is only given by the proton placed on y axis

E= kq/r^2 = 9*10^9* 1.6*10^-19/(3*10^-18)

= 4.8*10^8 N/C, directed to -y axis

b. Potential at origin

V= Ed= 4.8*10^8* 10^-9* sqrt(3)= 0.8314 V

According to chegg guidelinese can solve one problem at a time so please post other problems separately..

comment in case any doubt..goodluck
