MCQ
Which of the following group have different dimension
  • A
    Potential difference, $EMF$, voltage
  • B
    Pressure, stress, young's modulus
  • C
    Heat, energy, work-done
  • Dipole moment, electric flux, electric field

Answer

Correct option: D.
Dipole moment, electric flux, electric field
d
$Dipole memest=q \times d$

$Flux =A T L$

$Field =E . \Delta S=\frac{F}{q} \cdot \Delta S$
