The time period a satellite of earth is 5 hours. If the separation between the earth and the satellite in increased to four times the previous value, the new time period of the satellite will be

Options

  1. A20 hours
  2. B40 hours
  3. C80 hours
  4. D10 hours

Correct answer

B. 40 hours

Step-by-step solution

aligned & T ^2 r ^3 & T ₂^2 ~T ₁^2 = r ₂^3 r ₁^3 =(4)^3=64 & T ₂ ~T ₁ =8 or T ₂=8 ~T ₁=8 5=40 hours. aligned
