Answer:
Explanation:
As we know that when electron moved in electric field then work done by electric field must be equal to the change in kinetic energy of the electron
So here we have to find the work done by electric field on moving electron
So we have
now the distance moved by the electron is given as
so we have
now we have to convert it into keV units
so we have
Answer:
Explanation:
Given data:
if two charge are opposite in charge then force will be attractive between then or vice versa
if one charge is positive then other charge will be negative
from coulomb's law
Answer:
Hello There!!
