A balloon has `8g` of air `A` small hole is pierced into it The air escapes at a unifrom rate of `7cm//s` If the ballon shrinks in `5.6 s` then the average force acting on the ballon is.

A balloon has 8g of air A small hole is pierced into it The air escapes at a unifrom rate of 7m//s If the ballon shrinks in 5.6 s then the average force acting on the ballon is.

A balloon has 5 g of air. A small hole is pierced into it. The air escapes at a uniform rate with a velocity of 4 cm/s. If the balloon shrinks completely in 2.5 s, then the average force acting on the balloon is

A ballon has 2 g of air . A small hole is pierced into it . The air comes out with relative velocity 4 m/s . If the balloon shrinks completely in 2.5 s , the average force acting on the balloon is

A ballon has a mass of 5 g in air. The air escapes from the ballon at a uniform rate with a velocity of 5 cms^(-1) . If the ballon shrinks completely in 2.5 s, find the average foce acting on the ballon

A balloon has a mass of 10 gram in air. The air escapes from the balloon at a unifrom rate with a velocity of 5 cm //s and the balloon shrinks completely in 2.5 s . Calculate the average force acting on the balloon.

A hydrogen gas filled ballon having a mass of 25 g is released up in air . As the ballon descends , the gas starts leking from it with a unifrom velocity of 12 cm//s and as a result the balloon shrinks completely in 5 s . Find the average force acting on the ballon .
