This could maybe help you with your answer.
The kinetic energy of the electron is

where

is the mass of the electron and v its speed. Since we know the value of the kinetic energy,

, we can find the value of the speed v:
It takes 2 years of graduate study in a subfeild, practicum experience, and a thesis.

Answer:

Explanation:
As we know that EMF is induced in a closed conducting loop if the flux linked with the loop is changing with time
So we can say

now we have

here since magnetic field is constant so we have

now we have


now we have
