Q. A radiowave has a maximum magnetic field induction of $10^{- 4}$ T on arrival at a receiving antenna. The maximum electric field intensity of such a wave is
A) Zero
B) $3 \times 10^{4}\ Vm^{- 1}$
C) $5.8 \times 10^{- 4}\ T$
D) $3.0 \times 10^{- 5}\ T$
Explanation
(b) $E_{0} = cB_{0} = 3 \times 10^{8} \times 10^{- 4} = 3 \times 10^{4}\ Vm^{- 1}$
