Answer to Question #177745 in Electric Circuits for odunbun ibukun

Question

THE ELECTRIC FIELD NEAR A UNIFORM CHARGED CIRCULAR PLATE OF AREA 0.1m² is directed towards the plate and has the magnitude of 10⁴NC.calculate the charge density on the plate

Answer 1

For the plate $E=\frac{\sigma}{2\epsilon_0}$ .

So, we have

$\sigma=2\epsilon_0E=2\cdot8.85\cdot10^{-12}\cdot10^4=17.7\cdot10^{-8}\ (C/m^2)$ . Answer
