Question

According to one of the Kepler's laws of planetary motion :

पर्याय

• r² ∝ T³

• r ∝ T²

• r³ ∝ T²

• `r^3 ∝ 1/T^2`

Answer 1

r³ ∝ T²
According to Kepler’s third law of planetary motion, the cube of mean distance of a planet from the sun is directly proportional to the square of time it takes to move around the sun.
