A balloon and its content having mass M is moving up with an acceleration 'a'. The mass that must be released from the content so that the balloon starts moving up with an acceleration '3a' will be : (Take 'g' as acceleration due to gravity)
1
\(\frac{3 \mathrm{Ma}}{2 \mathrm{a}-\mathrm{g}}\)
2
\(\frac{3 \mathrm{Ma}}{2 \mathrm{a}+\mathrm{g}}\)
3
\(\frac{2 \mathrm{Ma}}{3 \mathrm{a}+\mathrm{g}}\)
4
\(\frac{2 \mathrm{Ma}}{3 \mathrm{a}-\mathrm{g}}\)
