Question

A parallel plate capacitor has a dielectric inserted fully between its plates, altering the surface charge density to $\sigma - \sigma_p$ . If the potential difference across the capacitor plates is given by $V = \frac{\sigma - \sigma_p}{\varepsilon_0}d$ , and the dielectric is linear, which of the following is true about the relationship between $\sigma$ and $\sigma_p$ ?

A

$\sigma_p$ is proportional to $\sigma$ .

B

$\sigma_p$ is inversely proportional to $\sigma$ .

C

$\sigma_p$ is independent of $\sigma$ .

D

$\sigma_p$ has no relation to $\sigma$ .

Accepted Answer

$\sigma_p$ is proportional to $\sigma$.

Answer

$\sigma_p$ is inversely proportional to $\sigma$.

Answer

$\sigma_p$ is independent of $\sigma$.

Answer

$\sigma_p$ has no relation to $\sigma$.
