Physics - Magnetism Question with Solution | TestHub

An$\alpha$-particle (mass$4$amu) and a singly charged Sulphur ion (mass$32$amu) are initially at rest. They are accelerated through a potential$V$and then allowed to pass into a region of uniform magnetic field which is normal to the velocities of the particles. Within this region, the$\alpha$-particle and the sulphur ion move in circular orbits of radii$R_{\alpha }$and$R_S$, respectively. The ratio$\left(\frac{R_S}{R_{\alpha }}\right)$is __________ .
