Question

Two charges $q_{1}$and $q_{2}$are placed in vacuum at a distance $d$ and the force acting between them is $F$. If a medium of dielectric constant 4 is introduced around them, the force now will be

• A. $4F$
• B. $2F$
• C. $\frac{F}{2}$
• D. $\frac{F}{4}$

Answer 1

Answer: (D)

$\frac{F}{4}$

Answer 2

In the presence of medium force becomes $\frac{1}{K}times$.
