If the air of weight $w$ is filled in an empty balloon which weighs $w_{1},$ the weight of the balloon will become $w_{2} .$ Suppose the density of the air inside and outside the balloon is same, then

Options:

Answer:

Solution:

The apparent weight of the balloon $= w_{2}$

Apparent weight = real weight - upthrust

∴ $w_{2} =$ real weight $- w$

But Real weight $= w_{1} + w$

$w_{2} = w_{1} + w - w = w_{1}$

$w_{2} = w_{1}$
