Two positively charged particles A and B having same kinetic energy move inside a transverse uniform magnetic field. The ratio of radius of path of charge A to that of charge B is 3/5, while mass of particle A is 4/9 times that of particle B. The ratio of charge on particle A to that of B is
(a) 9/10
(b) 10/9
(c) 2/5
(d) 5/3
