In the given expression $F = k\dfrac{q_1 q_2}{r^2}$, what does the constant $k$ represent in this content?
AMagnetic permeability
BGravitational constant
CDielectric constant
DElectric current constant
Answer & Solution
Correct answer: C. Dielectric constant
The provided content explicitly identifies $k$ as the dielectric constant in the relation $F = k\dfrac{q_1 q_2}{r^2}$. Therefore the correct choice is dielectric constant.
