In an electromagnetic wave, the electric and magnetising fields are `100 V m^(-1)` and `0.265 Am^(-1)`. The maximum energy flow is

A

`26.5 Wm^(-2)`

B

`36.5 Wm^(-2)`

C

`46.7 Wm^(-2)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Here, `E_(0) = 100 Vm^(-1)`,
`B_(0) = 0.265 Am^(-1)`
`:. `Maximum rate of energy flow, `S = (E_(0) xx B_(0))/(mu_(0))`
`= 100 xx 0.265 = 26.5 Wm^(-2)`
