A deuteron (the nucleus of an isotope of hydrogen) has a mass of 3.34×10?27kg and a charge of 1.60×10?19C. The deuteron travels in a circular path with a radius of 7.20mm in a magnetic field with a magnitude of 2.60T .
A) Find the speed of the deuteron.
B) Find the time required for it to make 1/2 of a revolution.
C) Through what potential difference would the deuteron have to be accelerated to acquire this speed?
