When air is replaced by dielectric medium of constant K, the maximum force of attraction between two charges separated by distance d, ..........

A

becomes `K_(2)` times

B

becomes `K^(-1)` times

C

becomes K times

D

remains unchanged

Text Solution

Verified by Experts

The correct Answer is:
B
`F. = F/K`
`F =(k_(q_(1)q_(2))/r^(2)), F. = k/K.(q_(1)q_(2))/r^(2)`
