Two planets Pi and P2 having masses Mi and M2 revolve around the Sun in elliptical orbits, with time periods Ti and T2, respectively. The minimum and maximum distances of planet Pi from the Sun are R and 3R, respectively, whereas for planet P2 these are 2R and 4R, respectively, where R is Q.16 a constant. Assuming Mi and M2 are much smaller than the mass of the Sun, the magnitude of is 2 M (A) 3 M2 (B)M O17 The

  • Ruby negi thankyou
    The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun.
