A man of weight w is in a lift which is moving up with an acceleration a.If acceleration due to gravity is g, apparent weight of the man will be

Mass of a balloon with its contents is 1.5kg. It is descending with an acceleration equal to half of acceleration due to gravity. If it is to go up with the same acceleration keeping the volume same, what amount of mass (in kg) should be decreased?
