two particles X and Y having equal charges, after being accelerated through the same potential difference, enter a region of uniform magnetic filed and describe circular paths of radii R1 AND R2 respectively. the ratio of the mass of X to that of Y is options a)R1/R2 WHOLE RAISED TO 1/2 b)R2/R1 c)R1/R2 the whole raised to 2 d)R1/R2

Expert Answer:

work done on each particle =qV
where V is potential difference and q is charge.
assuming particle starts from rest.The final kinetic energy will be
let magnetic feild be B then
magnetic force on each particle will be
this magnetic force is equal to centripetal force. Therefore
putting these values in equation 1 we get
therefore option C is correct
