Question

Hello people ~

When air is replaced by a dielectric medium of constant K, the maximum force of attraction between two charges separated by a distance
(a) increases K times
(b) remains unchanged
(c) decreases K times
(d) increases K^-1 times​

Answer 1

Step-by-step explanation:

In di electric medium

The force is

• 
  `\sf F_(dE)=(1)/(4K\pi\epsilon)(q_1q_2)/(R^2)`

So the force on air is decreased k times

Option C is correct
