An electroagnetic wave is propagating along x-axis. At x = 1 m and t = 10 s, its electric vector `|vecE|=6V//m` then the magnitude of its magnetic vector is

Options

A. `2xx10^(-8)T`
B. `3xx10^(-7)T`
C. `6xx10^(-8)T`
D. `5xx10^(-7)T`

Answer

A

Explanation

Here, `|vecE|=6V//m`
The magnitude of magnetic vector is
`|vecB|=(|vecE|)/(c)=(6V//m)/(3xx10^(8)m//s)=2xx10^(-8)T`
