Question

Two foxed insulating rings A and B carry charges with unifom
linear charge density +and -2, respectively, as shown in the
adjacent figure. The planes of the rings are parallel to each
other and their axes are coinciding. A particle of charge 9
and mass "m" is released with zero velocity from centre P of
the positively charged ring. The kinetic energy of the particle
when it reaches centre Q of the negatively charged ning wI'll be

(D) none of the above​
