Question 48 of 149

The electric flux is ϕ=ασ+βλ\phi=\alpha \sigma+\beta \lambda where λ\lambda and σ\sigma are linear and surface charge density, respectively. (αβ)\left(\frac{\alpha}{\beta}\right) represents

Show answer and solution

Answer: (D) displacement

α≡ϕσβ=ϕλαβ≡λσ≡ displacement \begin{aligned} & \alpha \equiv \frac{\phi}{\sigma} \\ & \beta=\frac{\phi}{\lambda} \\ & \frac{\alpha}{\beta} \equiv \frac{\lambda}{\sigma} \equiv \text { displacement }\end{aligned}
