The amplitude of electric field in an electromagnetic wave is `60 Vm^-1.` Then the amplitude of magnetic field is

A

`2 times 10^7 T`

B

`6 times 10^7 T`

C

`6 times 10^-7 T`

D

`2 times 10^-7 T`

Text Solution

Verified by Experts

The correct Answer is:
D
Amswer(4) Amplitude of electric field,`E_m = 60Vm^-1`
Amplitude of magnetic field, `_m = E_m/c = 60/3xx10^8` .
`therefore B_m = 2 xx 10^-7T`.
