As we learned

If dielectric medium is Partially filled between the charges -

\dpi{100} F=\frac{q_{1}q_{2}}{4\pi \varepsilon _{0}\left ( r-d+\sqrt{k}d \right )^{2}}

- wherein

 

 Effective air separation between them becomes infinite so force becomes zero.

 


Option 1)

2F\; \;

Option 2)

\frac{F}{2}\; \;

Option 3)

0\; \;

Option 4)

\sqrt{2}F
