A conducting ring of radius \( 1 \mathrm{~m} \) is placed in an uniform magnetic field \( B \) of \( 0.01 \mathrm{~T} \) oscillating with frequency
\( 100 \mathrm{~Hz} \) with its plane at right angles to \( B \). What will be the induced electric field?
(A) \( \pi \mathrm{V} / \mathrm{m} \)
(B) \( 10 \mathrm{~V} / \mathrm{m} \)
(C) \( 2 \mathrm{~V} / \mathrm{m} \)
(D) \( 62 \mathrm{~V} / \mathrm{m} \)
