Hello, let us understand the answer to the pt of the question.
00:04
Here we have to find the magnitude of the magnetic field in this case and the magnitude of magnetic field is equal to the magnitude of electric field divided by c.
00:10
It is already given the magnitude of electric field is already given that is equal to 8 ,000 newton per coulum divided by c that is equal to 3 multiple 10 to the power 8 and that is coming out to be about 2 .6 multiplied 10 to the minus 5 tesla.
00:24
So this would be the magnitude here the magnitude of the magnetic field in this case.
00:29
Now let us understand.
00:30
Understand the answer to the bit b of the question.
00:32
Here we have to find the energy density of the electric field and the energy density of the magnetic field.
00:37
The energy density of electric field is given by ue that equals 1 by 2, epsilon knot e square.
00:43
So putting all the values here...
