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 R1 and R2 respectively. The ratio of masses of X and Y is-
A
(R1/R2)1/2
B
(R2/R1)
C
(R1/R2)2
D
(R1/R2)
Answer
(R1/R2)2
Explanation
Solution
Kinetic energy KE = qV
Q V = same, q = same \ KE = same r µ 
; r µ
Q B = same
