1.	At its aphelion the planet mercury is 7 xx 10^(10) m from the sun & at its perihelion it is 4.5 xx 10^(10) m from the sun. IF the speed of mercury at aphelion is 3.6 xx 10^(4) m/s. then speed of it at perihelion is
Answer» `3.6 XX 10^(4)` m/s `5.6xx 10^(4)` m/s `1.6 xx 104` m/s MASS of mercury must be known to compute the requireed value from given INFORMATION Answer :B
