Electric Charge & Coulomb's Law

Two positively charged identical spheres separated by a distance 'd' exert some force (F) on each other when they are kept in air. If both the spheres are immersed in a liquid of dielectric constant 5, the force experienced by each is (All other parameters are unchanged.)

Show answer and solution

Answer: (d)

In a medium $F_m = \dfrac{F_{air}}{K}$ .
$F_m = \dfrac{F}{5}$
So the answer is (d) $\dfrac{F}{5}$ .
