Question

Two singly ionized isotopes of masses m₁ and m₂ pass through the same velocity selector and enter the same analyzer magnetic field. What is R₂/R₁?

G1 Physics · Accepted Answer

The selector gives both isotopes the same speed and their charge magnitudes are equal. Since R=mv/(qB), radius is directly proportional to mass.
