Maximum value of magnetic field of progressive electromagnetic wave is 20 nT, then maximum value of electric field is ………

Options

A. `12(V)/(m)`
B. `3(V)/(m)`
C. `6(V)/(m)`
D. `9(V)/(m)`

Answer

C

Explanation

`C=(E_(0))/(B_(0))`
`therefore E_(0)=CB_(0)=3xx10^(8)xx20xx10^(-9)`
`therefore E_(0)=6(V)/(m)`
