1. An electron enters a region of uniform magnetic field B = 0.05T (coming out of the page) with the speed 6.0 X 108 m/s, as shown below. Our goal is to calculate the ratio e/m (charge to mass ratio) using the concept of the centripetal force. We observe that radius of the electron's path is measured at r = 7.2 cm. (a) ( (b) (c) ( .) Draw the circular (a partial circle) path of the electron while in the region. ) Calculate e/m. (We do not need to know e or m individually! The adopted value for e/m is 1.76 X 1011 C/kg. Calculate the percent error.
