The mean intensity of radiation on the surface of the Sun is about `10^(s)W//m^2`. The rms value of the corresponding magnetic field is closed to :

A

`10^(-4)T`

B

`10^(-2)T`

C

`10^(2)T`

D

1 T

Text Solution

Verified by Experts

The correct Answer is:
A

`lt I gt = in_(0) E_(rms)^(2).C`
`E_(rms) = C.B_(rms)`
Putting values
B comes in order of `10^(-4) T`
