Question

1 An electron, traveling horizontally due North with a speed of 5.3×10^7 m/s , enters a region with a magnetic field of 87mT, pointing straight towards the West. a. What is the magnitude of the magnetic force on the electron? b. In what direction will the electron curve away from its original path? Give answer relative to E, W N, S, Up or Down. c. What is the magnitude of the acceleration of the electron? d. From the (centripetal) acceleration, determine the radius of curvature of the electrons path. 2 What electric field (vector!!) needs to be applied in problem 1 above if the electron is to travel un-deflected through the magnetic field? Give answer as magnitude and direction relative to E, W N, S, Up or Down.
