In a p-n junction having depletion layer of thickness \( 10^{-6} \mathrm{~m} \) the potential across it is \( 0.1 \mathrm{~V} \). The electric field is
(a) \( 10^{7} \mathrm{~V} / \mathrm{m} \)
(b) \( 10^{-6} \mathrm{~V} / \mathrm{m} \)
(c) \( 10^{5} \mathrm{~V} / \mathrm{m} \)
(d) \( 10^{-5} \mathrm{~V} / \mathrm{m} \)
\( \mathrm{P} \)
