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: |
A. | \(18.9 \times {10^{ - 8}}\hat k{\rm{\;T}}\) |
B. | \(2.1 \times {10^{ - 8}}\hat k{\rm{\;T}}\) |
C. | \(6.3 \times {10^{ - 8}}\hat k{\rm{\;T}}\) |
D. | \(18.9 \times {10^8}\hat k{\rm{\;T}}\) |
Answer» C. \(6.3 \times {10^{ - 8}}\hat k{\rm{\;T}}\) | |
