Q. 95.0( 3 Votes )

Two particles X and Y having equal charge, after being accelerated through the same potential difference enter a region of uniform magnetic field and describe circular paths of radii R1 and R2 respectively. The ratio of the mass of X to that of Y is
A. (R1/R2)1/2

B. R1/R2

C. (R1/T2)2

D. R1R2

Answer :

let the charge of both of them be q and mass be mx and my respectively. If they are driven through the same potential V then,


 


Thus, vx and vy (their respective velocities after leaving the potential) will be and


So from we get, (all the other terms are constant for both the particles)


So, according to the question


Thus,
