Question

Which of the following sets have different dimensions?

• A. Pressure, Young’s modulus, stress
• B. Emf, potential difference, electric potential
• C. Heat, work done, energy
• D. Dipole moment, electric flux, electric field

Answer 1

Answer: (D)

Dipole moment, electric flux, electric field

Answer 2

Dipole moment = charge × distance Electric flux = electric field × area

$\therefore$Dipole moment, electric flux and electric field have different dimensions.
