Two parallel conducting plates are separated by 16.0 cm. The region between the plates is immersed in a uniform magnetic field of 125 mT into the screen (-x direction) as shown below. How many volts must be applied across the plates to allow a 2.20 kev proton to go 1. undeflected? Which plate must be the positive plate? OA 2.20 kV, with the right plate positive and left plate negative O B. 13.0 kV, with the right plate positive and left plate negative OC 2.20 kV, with the left plate positive and right plate negative O D. 275 V, with the left plate positive and right plate negative O E. 13.0 kV, with the left plate positive and right plate negative
