1.	A planet moves around the sun of mass m in an ellipticcal orbit of eccentricity e. If a is the semi major axisof the elliptical orbit , the velocity of the planet at the apogee is given by
Answer» `SQRT((GM)/(a)[(1+e)/(1-e)])` `sqrt((Gm)/(a)[(1-e)/(1+e)])` `sqrt((2GM)/(a)[(1-e)/(1+e)])` `sqrt((2Gm)/(a)[(1+e)/(1-e)])` ANSWER :B
