Question

the magnitude of the magnetic field at point p for a certain electromagnetic wave is 2.21. What is the magnitude of the elctic field for that wave at P

Answer 1

`6.63* 10^8\ N/C`

Step-by-step explanation:

Given that,

The magnitude of magnetic field, B = 2.21

We need to find the magnitude of the electric field. Let it is E. So,

`(E)/(B)=c\\\\E=Bc`

Put all the values,

`E=2.21* 3* 10^8\\\\=6.63* 10^8\ N/C`

So, the magnitude of the electric field is equal to
`6.63* 10^8\ N/C`.
