In which of the following conditions, a Balloon filled with a gas such as Hydrogen will tend to rise up?

[A] If the buoyant force exerted by the air on a balloon is greater than the weight of the balloon

[B] If the buoyant force exerted by the air on a balloon is less than the weight of the balloon
[C] If the buoyant force exerted by the air on a balloon is equal to the weight of the balloon
[D] If the density of the air is greater than the density of the gas filled in balloon

  1. A [ If the buoyant force exerted by the air on a balloon is greater than the weight of the balloon]
    Notes:
    A Balloon filled with a gas such as Hydrogen gas is much lighter in weight than the weight of air displaced by it. So the buoyant force exerted by the air on a balloon is greater than the weight of the balloon. The hydrogen gas which is lighter than air enables the balloon to float.
