A plane electromagnetic wave of frequency 50 MHz travels in free space along the positive x-direction. At a particular point in space and time, \(\vec E = 6.3\hat j{\rm{\;V}}/{\rm{m}}\). The corresponding magnetic field \(\vec B{\rm{\;}}\), at that point will be:
1
\(18.9 \times {10^{ - 8}}\hat k{\rm{\;T}}\)
2
\(2.1 \times {10^{ - 8}}\hat k{\rm{\;T}}\)
3
\(6.3 \times {10^{ - 8}}\hat k{\rm{\;T}}\)
4
\(18.9 \times {10^8}\hat k{\rm{\;T}}\)
