Two particles move on a circular path (one just inside and the other just outside) with the angular velocities `omega` and `5omega` starting from the same point. Then

A

they cross each other at regular intervals of time `(2pi)/(4omega)` when their angular velocities are oppositely directed.

B

they cross each other at points on the path subtending an angle of `60^(@)` at the centre if their angular velocities are oppositely directed.

C

they cross at intervals of time `(pi)/(3omega)` if their angular velocities are oppositely directed

D

they cross each other at points on the path subtending `90^(@)` at the centre if their angular velocities are in the same sense.
