The transmitting antenna of a radio-station is mounted verticlly. At a point electric field is 10Km1 due north of the treansmitter the peak electric field is `10^(-3) "volt"//m` meter. The amplitude of the radiated magnetic magnetic field is:

A

`3.33xx10^(-10) tesla`

B

`3.33xx10^(-12) tesla`

C

`10^(-3) tesla`

D

`3xx10^(5) tesla`

Text Solution

Verified by Experts

The correct Answer is:
b

`B_(0)=(E_(0))/(c)=(10^(-3))/(3xx10^(8))=3.3xx10^(-12)T`
