The correct answer is:
\( 200 \mathrm{~V} / \mathrm{m} \)
(A)
\( E=\frac{V}{\alpha}=\frac{30-(-10)}{2 \times 10^{-2}}=2000 \mathrm{Vm}^{-1} \)
( \( \alpha= \) distance between two plates)
\( E=\frac{V}{\alpha}=\frac{30-(-10)}{2 \times 10^{-2}}=2000 \mathrm{Vm}^{-1} \)
( \( \alpha= \) distance between two plates)
