How do I start?
Problem: A helium nucleus (m= 6.65 x 10^-27 kg and q = 2e)is initially at rest. It is accelerated through a potential difference delta V and then enters a region with a constant magnetic field of strength B= 4T. It enter perpendicular to the field and undergoes circular motion with a radius of 0.001 m. Determine delta V?

Use the formula for the Larmor radius to get the velocity, v. You will find it at
Then compute the kinetic energy of the particle, KE = (1/2) m v^2
Use that to get deltaV
KE = q*(deltaV)
