Cherenkov discovered that a charged particle travelling with a speed exceeding the speed of light in material radiates electromagnetic radiation called Cherenkov light. Find the minimum kinetic energy in the unit of Joule that an electron must have while travelling in water (n=1.33) in order to create Cherenkov light. Note that the rest mass of an electron is 9.11x10-3ยน kg and the speed of light is 3.00x10 m/s.
