Electrostatics Question 174
Dielectric constant of pure water is 81. Its permittivity will be 81ε₀ [CPMT 1984]
Options:
A) $ 7.12\times {{10}^{-10}}\text{ MKS} $ units
B) $ 8.86\times {{10}^{-12}}\text{ MKS} $ units
C) $ 1.02\times 10^{13}\ \text{MKS} $ units
D) Cannot be determined
Show Answer
Answer:
Correct Answer: A
Solution:
$ \varepsilon =K{\varepsilon _{0}}=81\times 8.854\times {{10}^{-12}} \ \text{F/m}$
$ =7.17\times {{10}^{-10}}\text{ MKS units}$
