An electromagnetic wave is propagating along X -axis. At x=1 ~cm and t=18 ~s , its electric vector |E|=8 ~V / m , then the magnitude of its magnetic vector is
Options
- A266 10⁻⁸
- B3 10⁻⁷
- C3.14 10⁻⁸
- D3.16 10⁻⁷
Correct answer
A. 266 10⁻⁸
Step-by-step solution
As we know that, E B =c so, B= E c = 8 3 10^8 =2.66 10⁻⁸
