- MCQ
Which of the following physical quantities have the same dimensions?
Pick an option to check your answer.
Answer & Solution
Correct Answer
(A) Electric displacement \((\overrightarrow{ D })\) and surface charge density
Step-by-step Solution
Detailed explanation
Electric displacement
\(\overrightarrow{ D }=\epsilon_{0} \overrightarrow{ E }\)
\([ D ]=\left[\epsilon_{0} E \right]=\left[\epsilon_{0} \frac{\sigma}{\epsilon_{0}}\right]\)
\([ D ]=[\sigma]\)
\(\rightarrow\) Surface change density \(=\sigma\).
