A beam consists of ^1H and ^2H nuclei traveling at a constant horizontal velocity. The beam enters a uniform, vertical magnetic field of 0.500 T. The ^2H nuclei follow a circular arc of radius 55.6 cm. Find the radius of the circular arc followed by the ^1H nuclei. Let the mass of an ^1H nucleus (a proton) m1 = 1.67 x 10^-27 kg, the mass of an ^2H nucleus ( a deuteron) m2 = 3.34 x 10^-27 kg, and the charge on a proton q = 1.60 x 10^-19 C

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
