SIR 31 a [Total 5 marks) P4: One electron with an energy of 189 eV is moving in a circular path and uniform magnetic field of magnitude 70 ut. The magnetic fielded is perpendicular to the velocity vector. Find (a) the frequency of revolution of the electron. [2.5 marks] (b)the radius of the circular path of the electron [2.5 marks] 1 eV = 1.6x10-19J me = 9.11x10-31 kg
