The average electric field of electromagnetic waves in certain region of free space is `9 xx 10^(–4) NC^(–1)`. Then the average magnetic field in the same region is of the order of

A

`27 xx 10^(-4)`

B

`3 xx 10^(-12)T`

C

`((1)/(3)) xx 10^(-12)T`

D

`3 xx 10^(12)` T

Text Solution

Verified by Experts

The correct Answer is:
B
`B= (E)/(c)= (9 xx 10^(-4))/(3 xx 10^(8))= 3 xx 10^(-12)` T
