Question

The dimensions of electric dipole moment are

• A. $[L^{2}I]$
• B. $[LI]$
• C. $[LTI]$
• D. $[T^{-2}]$

Answer 1

Answer: (C)

The electric dipole moment is
$P=qd=itd$
The dimensions of electric dipole moment is
$\left[p\right]=\left[i\right]\left[t\right]\left[d\right]$
$=\left[I\right]\left[T\right]\left[L\right]$
$=\left[LTI\right]$
