Answer:
The strength of the electric field is
Explanation:
Here the electric force is equal to Newton's second law.

Let's recall that electric force is the electric field times the charge, so we have:

(1)
Where:
m is the proton mass
q is the proton charge
a is the acceleration
Using the equation (1) we have:
Therefore, the strength of the electric field is

The optical fibers are thin, thus, the light entering from one side of the wire surface has more chances to reflect back from the inside surface due to the larger angle of incidence.
The angle of the strike is large due to the small size of the wire and this angle is greater than the critical angle.
As the angle of the incident light on the inside surface is greater than the critical angle, thus, the total internal reflection of the takes place.
Hence, there are more chances of total internal reflection of light inside the optical fiber wire than the emergence of light through the wire.
