The electron was first discovered by Sir J.J. Thomson in 1897 at the Cavendish Laboratory in Cambridge, England. His experimental apparatus is not very different from the one which you will use in this lab, and he was later awarded the Nobel Prize for his discovery. You will be doing some Nobel Prize winning work in this lab! A charged particle traveling in a uniform magnetic field which is perpendicular to its velocity will travel in a circular path. Using a combination of Newton's second law and the force of the magnetic field, the circular motion of a charged particle moving in a magnetic field can be described as: ||F| = q|v||B| : m|5|2 r (2) Recall that the velocity of a charged particle is dependant on its kinetic energy. Using the conservation of energy the charged particle's kinetic energy can be simplified as equal to its electric potential energy given by equation 2: 1 mv =qAV (3) By relating the relationship between the kinematics of the particle and its energy, one can derive an equation solving for the charge to mass ratio of the particle. With the given equipment, collect data related to the motion of a charged particle in a magnetic field. Using the data collected, determine a relationship that will lead to the calculation of the charge to mass ratio of the particle. Compile your findings into a lab report, answering relevant discussion questions. The electron was first discovered by Sir J.J. Thomson in 1897 at the Cavendish Laboratory in Cambridge, England.
