  • A
    0 volts/meter
  • B
    $\frac{\sigma}{2 \varepsilon_0}$ volts/meter
  • ✓
    $\frac{\sigma}{\varepsilon_0}$ volts/meter
  • D
    $\frac{2\sigma}{ \varepsilon_0}$ volts/meter
✓

Answer

Correct option: C.
$\frac{\sigma}{\varepsilon_0}$ volts/meter
(c) $\frac{\sigma}{\varepsilon_0}$ volts/meter

$(iv)$ The sensitivity of the galvanometer, when using a potentiometer is not relevant.
Which of these reasons are correct?
