An earth's satellite nejar the surface of the earth takes about 90 min per revolution. A satellite orbiting the moon also takes about 90 min per revolution. Then which of the following is true?

Options:

Answer:

Solution:

Hint :
$m (E_{g}) = m ω^{2} R$ $m \cdot 4 π \frac{GρR}{3} = m ω^{2} R \Rightarrow ω^{2} \propto ρ \Rightarrow T \propto \frac{1}{ρ}$ If $T$ are equal, so will be $ρ$
