which of the following does not have the same dimension? |
Electric Flux , Electric Field , Electric dipole moment Pressure , Stress , Young's Modulus Electromotive force , potential difference , Electric Voltage Heat , Potential Energy , Work Done |
Electric Flux , Electric Field , Electric dipole moment |
2. Pressure = $\frac{Force}{Area}$ Stress = $\frac{Force}{Area}$ Youngs modulus : $\frac{Stress}{Strain}$ Since strain is dimensionless so all three have same dimension. 3. Electromotive force = $\frac{Energy}{Charge}$ Potential difference = $\frac{W}{Q}$ which is same as Electromotive force. Electric voltage = $\frac{Electric Energy}{Charge}$ All three have same dimension. 4. Heat , Potential energy and work done all have same dimension. |
