Q. Two particles, P and Q are initially at two ends of a circular arc which subtends an angle 120o at the arc-center. The radius of the arc is r. The particles P and Q are moving along the arc towards each other with constant tangential velocities of VP and VQ respectively. The distance travelled by the particle P when it meets the particle Q is
- 2π3r(VP+VQ)VP
- 2π3r(VP+VQ)VQ
- 2π3rVP(VP+VQ)
- 2π3rVQ(VP+VQ)

Q. A mass 'M' is suspended from a ceiling through a string of length 'L'. This mass moves in a circle of horizontal radius 'r'. at constant speed such that it is a conical pendulum. The tension in the string will-be

- mgL/√r2
- mgL/(√L2−r2)
Q. A mass attached to a string is swung in a circular path with a uniform angular velocity about the horizontal plane, as shown. Seen directly from above, which path would the mass most closely follow if the string breaks suddenly at T?
