Question

The dimensional formula for electric dipole moment is:

Options

• \[M^0L^0T^0A^0\]

• \[M^0L^1T^1A^1\]

• \[M^1L^1T^{-2}\]

• \[M^1L^2T^{-3}A^{-1}\]

Answer 1

The dipole moment \[\vec{p} = q \times d\] has dimensions where q is charge (amperes × seconds = A·T) and d is distance (L). Therefore, the dimensional formula is \[M^0L^1T^1A^1\], representing length (L), time (T), and current (A) components without mass (M).
