The magnetic field in a travelling electromagnetic wave has a peak value of 20nT20 nT. The peak value of electric field strength is :

Options

  1. A9Vm−19 V {m}^{- 1}
  2. B12Vm−112 V {m}^{- 1}
  3. C3Vm−13 V {m}^{- 1}
  4. D6Vm−16 V {m}^{- 1}

Correct answer

D. 6Vm−16 V {m}^{- 1}

Step-by-step solution

E=Bc=20×10−9×3×108E = Bc = 20 \times {10}^{- 9} \times 3 \times {10}^{8}

=6 V/m= \text{6 V/m}
