A deuteron consists of one proton and one neutron. A deuteron moving horizontally enters a uniform, verticle magnetic field of 0
.500 T. It then travels in a circular arc 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. 7.52*10^6 m/s
3.34*10^7 m/s
9.94*10^7 m/s
1.33*10^7 m/s
