Question

Two particles `X` and `Y` having equal charges, after being acceleration 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 the mass of `X` to that of `Y` is
A. `(R_1//R_2)^(1//2)`
B. `R_2//R_1`
C. `(R_1//R_2)^2`
D. `R_1//R_2`

Answer 1

`R=sqrt((2qVm)/(Bq)`
or `Rpropsqrtm`
or `R_1/R_2=sqrt(m_X/m_Y)`
or `m_X/m_Y=(R_1/R_2)^2`
`:.` correct option is c.
