If relative permittivity for any substance is 80 then its electric susceptibility is _________.
- A \(81 \times 10^{-10}\)
- B \(7 \times 10^{-10}\)
- C 79
- D \(7 \times 10^{-9}\)
Answer & Solution
Correct Answer
(C) 79
Step-by-step Solution
Detailed explanation
(C)
\(\begin{aligned} K & =1+\chi_e \quad\left(\chi_e \text { unit less }\right) \\ \therefore \quad 80 & =1+\chi_e \\ \therefore \quad \chi_e & =80-1=79\end{aligned}\)
\(\begin{aligned} K & =1+\chi_e \quad\left(\chi_e \text { unit less }\right) \\ \therefore \quad 80 & =1+\chi_e \\ \therefore \quad \chi_e & =80-1=79\end{aligned}\)
