Two particles A and B with the same charges and different masses (m1 and m2 respectively) are moving in a plane inside a uniform magnetic field which is perpendicular to the plane. Then:
a) Both particles move in the same circle.
b) Particle A moves in a smaller circle compared to particle B.
c) Particle B moves in a smaller circle compared to particle A.
d) The paths of particles A and B are straight lines.
