The unit of Intensity of polarization is _________ .
- A \(\frac{ C ^2}{m}\)
- B \(\frac{ C }{m^2}\)
- C \(\frac{ C ^2}{m^2}\)
- D \(\frac{m^2}{ C }\)
Answer & Solution
Correct Answer
(B) \(\frac{ C }{m^2}\)
Step-by-step Solution
Detailed explanation
(B)
Intensity of polarization
\(P =\frac{ P _{\text {total }}}{\text { volume }}=\frac{\left(\sigma_b A\right) d}{A d}=\sigma_b\)
\(=\frac{ C }{m^2}\)
Intensity of polarization
\(P =\frac{ P _{\text {total }}}{\text { volume }}=\frac{\left(\sigma_b A\right) d}{A d}=\sigma_b\)
\(=\frac{ C }{m^2}\)
