Question

you changes placed in vacuum experience force of 4*10-³ n if a dielectric medium of k=2 dielectric constant is placed in between them.calculate the new force​

Answer 1

F= kq1q2/r²

F=2×q1q2/4π€€r

Force is inversely proportional to dielectric constant of the medium

F1=F/2=2×10^-3

I hope this helps
