In one experiment, an electron is accelerated from rest through potential V₁, enters normally into a uniform magnetic field B, and moves in a circular path of radius r. In a second experiment, the magnetic field is increased to 3B and the electron is observed to move in a circular path of radius 2r. If the second accelerating voltage is V₂ = NV₁, find N.
