ing tavern a circular arc of faults was .24 An electron is accelerated from rest by a potential differ- ence of 350 V. It then enters a uniform magnetic field of magni- tude 200 mT with its velocity perpendicular to the field. Calculate (a) the speed of the electron and (b) the radius of its path in the magnetic field. a) For problem .24a (part a), what would the velocity of the electron (in units of 107 m/s) be if the electron were accelerated by a voltage difference of 285 V? 5 sig figs b) In Problem 28.24's part b, assume an inbound velocity (the value you would calculate in part (a)) of 1.11 x 107 m/s and a magnetic field of B = 0.29 T, and solve for the radius of the circular path in micrometers. 5 sig figs
