Explanation:
From the question we are told that
The magnitude of electric dipole moment is
The electric field is
The distance between the positive and negative charge center is mathematically evaluated as
Where e is the charge on one electron which has a constant value of
Substituting values
The maximum torque is mathematically represented as
Here
This because at maximum the molecule is perpendicular to the field
substituting values
The workdone is mathematically represented as
where is the potential energy at 180° which is mathematically evaluated as
Where the negative signifies that it is acting against the field
substituting values
and
is the potential energy at 0° which is mathematically evaluated as
substituting values
So
Answer:
c.
Explanation:
Electromagnetic waves are waves that are generated when an electric field and a magnetic field vibrate together. They are usually created whenever an electric field collides with a magnetic field.
In more generic terms for an electric field, the energy per unit volume is given by:
Energy density =
For magnetic field:
Energy density =
∴
For the electromagnetic wave (u):
Total energy density is:
Due to the fact that the energy related with both fields is equivalent:
Then:
E = cB
