If air of weight w is filled in a empty ballon which weights `w_(1)` the weight of ballon will become `w_(2)` Suppose the density of air inside and out side the vallon is same, then,

An empty balloon weighs W_(1) . If air equal in weight to W is pumped into the balloon, the weight of the balloon becomes W_(2) . Suppose that the density of air inside and outside the balloon is the same. Then

An empty balloon weighs W . If air equal in weight to W is pumped into the balloon, the weight of the balloon becomes W_(2) . Suppose that the density of air inside and outside the balloon is the same. Then

A body of weight W is floating in a liquid. Its apparent weight will be :

A soft plastic bag of weight w_(0) is filled with air at STP Now, weigth of the bag is w in air. Then,
