Asatellite is put in a circular orbit about earth with a radius equal to 35% of the radius of the moon's orbit. what is its period of revolution in lunar months? (a lunar month is the period of revolution of the moon.)

0.21 lunar month

Explanation:

the radius of moon = r₁

time period of the moon = T₁ = 1 lunar month

The radius of the satellite = 0.35 r₁

Time period of satellite

The relation between time period and radius

now,

                              T₂ = 0.21 lunar month

hence, the time period of revolution of satellite is equal to 0.21 lunar month

think its the third option
