A deuteron particle (the nucleus of an isotope of hydrogen consisting of one proton and one neutron and having a mass of (3.34×10−27 kg ) moving horizontally enters a uniform, vertical, 0.520 T magnetic field and follows a circular arc of radius 58.0 cm .

Part A

How fast was this deuteron moving just before it entered the magnetic field ?

v1=

m/s

Part B

How fast was this deuteron moving just after it came out of the field?

v2=

m/s

Part C

What would be the radius of the arc followed by a proton that entered the field with the same velocity as the deuteron?

R= cm
