A planet revolving round the sun. Its distance from the sun at apogge

1.	A planet revolving round the sun. Its distance from the sun at apogge is r_(A) and that at perigee is r_(P). The masses of planet 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 worn answer.
Answer» <P>`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 :B
