I'm not sure I completely understand the expression you want evaluated.
It looks like a fraction with the same exact thing in both the numerator and the denominator. A fraction like that always boils down to ' 1 '.
Answer:
The value of new coulomb force is 1.43 N.
Explanation:
Given;
Coulomb's force in vacuum (air), = 10 N
dielectric constant, K = 7
The Coulomb's force between two charges separated by a distance r in a vacuum is given as;
The Coulomb's force between two charges separated by a distance r in a medium with dielectric constant is given as
Take the ratio of the two forces;
Therefore, the value of new coulomb force is 1.43 N.
