Question

a) An electron in a Hydrogen atom moves around in a circular orbit of radius 0.51 x um Suppose the hydrogen at s ran Porte into a ma ne i T, where the magnetic field is parallel to the orbital angular momentum. At what frequency does the electron revolve in the magnetic field? 1.96x1010 1s You are correct. Computer's answer now shown above Your receipt is 163-2822 ted of D70 Previous Tries b) What is the associated speed of the electron? Assume that the radius of the orbit remains constant 6.27 m/s You are correct. Computer's answer now shown above Your receipt is 163-9363 Previous Tries c) Imagine the electron is initially traveling at a speed of 2.90 x 10° m/s, what is the change in the kinetic energy of the electron when it is introduced in the magnetic field? 23.9 ev Submit Answer Incorrect. Tries 3/6 Previous Tries

Explanation / Answer

Change in kinetic energy= final- initial kinetic energy= 0.5*mass of electron*( 6.27^2- 2900000^2) = 3.83*10^-18J = 23.9081 eV
