1.	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 velocityof 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.
Answer» `T^2=pi^2/(2GM)(r_A+r_P)^3` `T^2=pi^2/(2GM)(r_A+r_P)^2` `v_A r_A = v_P r_P` `v_A lt v_P , r_A gt r_P` Answer :D
