A planet is revolving round the sun. Its distance from the sun at apogee is `r_A` and that at perigee is `r_p` . The masses of plancet and sun are .m. and M respectively, `v_A` is the velocity of planet at apogee and `v_p` is at perigee respectively and T is the time period of revolution of planet round the sun, then identify the wrong answer.

Options

A. `T^(2)=(pi^2)/(2GM)(r_A+r_P)^3`
B. `T^(2)=(pi^2)/(2GM)(r_A+r_P)^2`
C. `v_Ar_A=v_pr_P`
D. `v_A lt v_p , r_A gt r_p`

Answer

D
