According to Kepler's law of planetary motion, if

T

represents time period and

r

is orbital radius, then for two planets these are related as

View answer and explanation

Correct option: C

\left[\frac{T_1}{T_2}\right]^2=\left[\frac{r_1}{r_2}\right]^3

Option C (

\frac{T_1}{T_2}^2=\frac{r_1}{r_2}^3

) is correct because it represents Kepler's Third Law, which relates the period and orbital radius of planets.
