1.	A balloon of mass M is descending at a constant acceleration alpha. When a mass m is released from the balloon it starts rising with the same acceleration alpha . Assuming that its volume does not change, what is the value of m?
Answer» `(ALPHA)/(alpha+g)M` `(2ALPHA)/(alpha+g)M` `(alpha+g)/(alpha)M` `(alpha+g)/(2alpha)M` SOLUTION :While DESCENDING, `Mg=F_(B)=Malpha` While ascending`F_(B)-(M-m)g=(M-m)alpha` where `.F_(B).` is the bouyant force
