A particle is moving with a uniform speed in a circular orbit of radius R in a central force inversely proportional to the nth power of R. If the period of rotation of the particle is T, then:

  • A.TR(n+1)/2T \propto R^{(n + 1) / 2}Correct
  • B.TRn/2T \propto R^{n / 2}
  • C.TR3/2T \propto R^{3 / 2}   for any n.
  • D.TRn2+1T \propto R^{\frac{n}{2} + 1}
