Gravitation

A satellite is orbiting just above the surface of the earth with period TT. If dd is the density of the earth and GG is the universal constant of gravitation, the quantity 3πGd\dfrac{3\pi}{Gd} represents:

  1. A.TT
  2. B.T2T^2✓
  3. C.T3T^3
  4. D.T\sqrt{T}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
