MCQ
Two particles $X$ and $Y$ having equal charges, after being accelerated through the same potential difference, enter a region of uniform magnetic field and describe circular paths of radii $R_1$ and $R_2$ respectively. The ratio of masses of $X$ to that of $Y$ is:
  • A
    $\Big(\frac{\text{R}_1}{\text{R}_2}\Big)^{\frac{1}{2}}$
  • B
    $\Big(\frac{\text{R}_2}{\text{R}_1}\Big)$
  • $\Big(\frac{\text{R}_1}{\text{R}_2}\Big)^2$
  • D
    $\Big(\frac{\text{R}_1}{\text{R}_2}\Big)$

Answer

Correct option: C.
$\Big(\frac{\text{R}_1}{\text{R}_2}\Big)^2$
