Question

The dimensional formula of electric flux is.

• A. $\lbrack M^{1}L^{1}T^{- 2}\rbrack$
• B. $\lbrack M^{1}L^{3}T^{- 3}A^{- 1}\rbrack$
• C. $\lbrack M^{2}L^{2}T^{- 2}A^{- 2}\rbrack$
• D. $\lbrack M^{1}L^{- 3}T^{3}A^{1}\rbrack$

Answer 1

Answer: (B)

$\lbrack M^{1}L^{3}T^{- 3}A^{- 1}\rbrack$

Answer 2

: Electric flux, $\varphi = \int_{}^{}{\overrightarrow{E}.d\overrightarrow{s}}$

The dimension of $\varphi =$Dimension of E × dimension of $d\overrightarrow{s}$

$= \lbrack M^{1}L^{1}T^{2}\rbrack\lbrack L^{2}\rbrack\lbrack AT\rbrack^{- 1}$ $= \lbrack M^{1}L^{3}T^{3}A^{- 1}\rbrack$
