Question

a balloon of mass M is descending with a constant acceleration g/3. when a mass m is released from the balloon it starts rising with the same acceleration g/3. the value of m is.(volume is constant)

Answer 1

While descending

R = M(g - a)

R = M(g - g/3)

R = 2Mg/3

While rising

R = (M - m)(g + a)

2Mg/3 = (M - m)(g + g/3)

2Mg/3 = (M - m)4g/3

M = (M-m)2

M/2 = M - m

m = M - M/2

m = M/2

Mass to be removed is M/2

hope this helps you
