G Two planets are in circular orbits around a star of with unknown mass. One planet is orbiting at a distance r1=150×106 km and has an orbital period T1=240 days. The second planet has an orbital radius r2=230×106 km. Find the orbital period of the second planet T2.

Time period of second planet will be 126.40 days

Explanation:

We have given radius of first planet

Orbital speed of first planet

Radius of second planet

We have to find orbital period of second planet

Period of orbital is equal to

From the relation we can see that

Time period of second planet will be 126.40 days

456 days.

Explanation:

Given,

r₁ = 150 x 10⁶ Km

r₂ = 230 x 10⁶ Km

T₁ = 240 days

T₂ = ?

Using Kepler's law

Now,

Time taken by the second planer is equal to 456 days.
