Vittorio needs to clean the dusty mirror hanging on the wall beforehe can use it, but he would like to clean as little of the mi
rroras possible.
Vittorio would like to be able to see the logo on his shirt.Draw the incident and reflected raysshowing the light from the logo reflecting off the mirror into hiseyes. The rays should meet at the point on the mirror that needscleaning.

Answer:
The drawing is attached below.
Explanation:
According to the drawing, we can see that the point "0" marked on the mirror, is the point that allows the formation of an angle between Vittorio's eyes and the place where his shirt logo is. In summary, the point on the mirror that needs to be cleaned, so that Vittorio can see only the logo of his shirt, is the point that represents equal vertical distances between Vittorio's eyes and the shirt's logo, since these distances present the same angle.

To solve this problem it is necessary to apply the concepts related to the magnetic field.
According to the information, the magnetic field INSIDE the plates is,
Where,
Permeability constant
Electromotive force
r = Radius
From this deduction we can verify that the distance is proportional to the field
Then the distance relationship would be given by
On the outside, however, it is defined by
Here the magnetic field is inversely proportional to the distance, that is
Then,
