1.	A planet of mass m is revolving round the sun (of mass M_(s) in an elliptical orbit. If vecv is the velocity of the planet when its position vector from the sun is vecr, then areal velocity of the positon vector of the planet is :
Answer» `VECV + VECR` `vecrxx vecv` `1/2(vecv xxvecr)` `1/2(vecrxx vecv)` ANSWER :D
