Answer:
Explanation:
This problem can be solved by the following equation:
Where:
is the change in kinetic energy
is the electric potential difference
is the electric charge
Finding :
Finally:
To solve this problem we will resort to the concept of angle of incidence and refraction.
Since it is a reflection on a mirror, the angle provided for refraction will be equal to that of the incidence, that is, 25 °
The angle of reflation is always perpendicular to the surface so it is necessary to find the angle with respect to it.
Therefore the angle of the reflected beam of light made with the surface normal is 65°
