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

A

`2 xx 10 ^(-8) T`

B

`3 xx 10 ^(-7) T`

C

`6xx 10 ^(-8) T`

D

`5xx 10 ^(-7) T`

Text Solution

Verified by Experts

The correct Answer is:
A
Here, `|vecE| = 6 V//m`
The magnitude of magnetic vector is
`|vecB| = (|vecE|)/(c ) = (6 V //m)( 3 xx 10 ^(8) m //s) = 2 xx 10 ^(-8) T`
