Options:
A) $ 7.12\times {{10}^{-10}}MKS $ units
B) $ 8.86\times {{10}^{-12}}MKS $ units
C) $ 1.02\times 10^{13}\ MKS $ units
D) Cannot be calculated
Show Answer
Answer:
Correct Answer: A
Solution:
$ \varepsilon =K{\varepsilon _{0}}=81\times 8.854\times {{10}^{-12}} $
$ =7.17\times {{10}^{-10}}MKSunits $
