The rotation period of an earth satellite close to the surface of the earth is 83 minutes. The time period of another earth satellite in an orbit at a distance of three earth radii from its surface will be |
83 minutes 83 × $\sqrt{8}$ minutes 664 minutes 249 minutes |
664 minutes |
T2 = k R3 ; T2 = k(4R)3 $\frac{T'^2}{T^2}$ = 64, T' = 8T = 8 × 83 = 664min |
