A satellite is orbiting just above the surface of the planet of density ' ' with periodic time ' T '. The quantity T ^2 is equal to ( G = universal gravitational constant)

Options

  1. A4 ^2 G
  2. B3 ^2 G
  3. C3 G
  4. DG

Correct answer

C. 3 G

Step-by-step solution

Time period of a nearby satellite is given by, aligned & T=2 R g & T^2=4 ^2 R g & But, g= 4 3 G R . & T^2= 4 ^2 R 4 3 G R & T^2 = 3 G aligned
