Consider a gas bubble which is initially trapped at atmospheric pressure behind the barrier in the continuation of the same, dead-ended channel having a dead volume of 10 l. The inner end of the liquid segment in part (b) is open to atmosphere. Now the barrier is suddenly removed while spinning at 20 Hz, what would be the radial position of the outer meniscus of the liquid in the new pressure equilibrium? (Assume that the cross section of the channel is sufficiently small so that surface tension maintains the integrity of the liquid segment, which thus acts like a solid piston of the same density as the liquid.)
