Mathematics · Gravitation
Two planets P1 and P2 having masses M1 and M2 revolve around the sun in elliptical orbits with time periods T1 and T2 respectively. The minimum and maximum distances of planet P1 from the sun are R and 3R respectively. Whereas for planet P2, these are 2R and 4R respectively. Assuming M1 and M2 are much smaller than the mass of the sun, the magnitude of the ratio T2/T1 is:
- 132 √32✓
- 223 √32
- 332 √3 M12 M2
- 423 √2 M13 M2
Correct answer
32 √32
