Two particles move on a circular path (one just inside and the other just outside) with angular velocities ω and 5ω starting from the same point. Then which of the following is incorrect?

Options

• Option A

  For opposite angular directions, crossing interval=2π/(4ω)

• Option B

  For opposite directions, crossing points subtend 60° at the centre

• Option C

  For opposite directions, crossing interval=π/(3ω)

• Option D

  For same angular direction, crossing points subtend 90° at the centre
