Physics20222 marksShort answer
A parallel plate capacitor of plate area $A = 600\text{ cm}^2$ and plate separation $d = 2.0\text{ mm}$ is connected to a dc source of $200\text{ V}$.
(i)[1.0]
What is the magnitude of the uniform electric field E between the plates?
  • (a)$E = 1.0 \times 10^5\text{ V/m}$
  • (b)$E = 1.0 \times 10^7\text{ V/m}$
  • (c)$E = 0.5 \times 10^5\text{ V/m}$
  • (d)$E = 0.5 \times 10^7\text{ V/m}$
(ii)[1.0]
What is the charge density $\sigma$ on any one of the two plates?
  • (a)$\sigma = 8.85 \times 10^{-7}\text{ C/m}^2$
  • (b)$\sigma = 8.85 \times 10^{-9}\text{ C/m}^2$
  • (c)$\sigma = 4.45 \times 10^{-7}\text{ C/m}^2$
  • (d)$\sigma = 4.45 \times 10^{-9}\text{ C/m}^2$
