Q. The dimensional formula for electric flux is
AIIMS
AIIMS 2015
A
$\left[ ML ^{3} I ^{-1} T ^{-3}\right]$
B
$\left[M^{2} L^{2} I^{-1} T^{-2}\right]$
C
$\left[ ML ^{3} I ^{1} T ^{-3}\right]$
D
$\left[ ML ^{-3} I ^{-1} T ^{-3}\right]$
Solution:
As electric flux is given by
$\phi_{E} =E d s=\frac{F}{q} d s $
$\therefore $ Dimensions of $ \phi =\left[\frac{ ML T ^{-2}}{ IT }\right]\left[ L ^{2}\right] $
$=\left[ M L ^{3} I ^{-1} T ^{-3}\right]$
