Explanation / Answer

Electric field E = KQ/r^2

here Since both happens to be same charges,

Net EF will be zero in between them

let this be at x units from origint to wards the right

so q2 is at a distance of (x+d) and q1 is at a distance of (d-x)

so for NET EF at this point to be zero,

E1 = E2

Kq1/(d-x)^2 = kq2/(d+x)^2

(d+x)/(d-x)^2 = q2/q1 = 2.35/0.55 = 4.2727272

d+x/(d-x) = 2.067

d+x = 2.067 d - 2.067 x

1.067 d = 3.067 x

x = 1.067 * 0.038/3.067

x = 0.0132 m is the distance where EF is zero
