A deuteron consists of one proton and one neutron. A deuteron moving horizontally enters a uniform, vertical magnetic field of 0.500 T. It then travels in a circular arc of radius 55.6 cm. How fast was the deuteron moving just before it entered the field? Let the mass of the deuteron m = 3.34 × 10^–27 kg and the charge on a proton q = 1.60 × 10^–19 C. (1 point)

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
