1. a proton is first accelerated from rest through a potential difference v and then enters a uniform 0.750-t magnetic field oriented perpendicular to its path. in this field, the proton follows a circular arc having a radius of curvature of 1.84 cm. what was the potential difference δv? sketch the situation and start newton’s second law and conservation of energy to derive the equations you use to solve the problem. (mproton = 1.67 × 10-27 kg)

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
