I try to do illusteation 15 in same way as 16 but i cant get ryt answer.....
But... my doubt is how we can do illustration 16 with out considering force due to rate of change of mass... i think since it loss mass... we must add extra force rv ( r = rate of change of mass and v is velocity at that instant ) .... plzzz say what is my mistakes.
