Which of the following pairs have different dimensions?

Options

A. Potential difference, EMF, voltage
B. Pressure, stress, young's modulus
C. Heat, energy, work-done
D. Dipole moment, electric flux, electric field

Answer

D

Explanation

Dipole moment `=q(2a)implies [P]=[ATL]`
Electric flux `(phi) = EA cos theta rarr [MLT^(-2)A^(-1)T^(-1)L^2]`
`= [ML^(3)T^(-3)A^(-1)]`
Electric field (E) `=F/q = [ML^(3)T^(-3)A^(-1)]`
All have different dimensions.
