Question

the force between the 2 charges in air medium is f now the air medium between them is replaced by an oil medium of dielectric constant k the new force between ch arge will be
​

Answer 1

Explanation:

By Coulomb's law, the force between two charges (q

1

,q

2

) in air is given by F=

4πϵ

0

r

2

q

1

q

2

where r= distance between two charges.

Now the force between two charges (q

1

,q

2

) in medium with dielectric constant K=4 becomes, F

′

=

4πKϵ

0

r

q

So, F

F

=
