Question

When air is replaced by a distance medium constant k, the maximum force of attraction between two charges separated by a distance 1
1)increase k-2
2)increase k times
3)decrease k times
4) remains constant​

Answer 1

Answer:

In air the force of attraction between two charges is F

a =4πϵ 0 1 r 2 q 1 q 2 In dielectric medium the force of attraction between two charges is F d = 4πKϵ 0 1 r 2 q1

q 2 = K F a Thus, force decreases K-times
