    The total weight o a gas filled balloon is 1500N.

    but how much magnitude of buoyant foce will be there when balloon continously arises up?

    The total weight o a gas filled balloon is 1500N.

    as given that the speed is constant ,so there is no acceleration in the ballon.and according to Newton 2nd law,force acting on the object is directly proportional to mass of the objectand accelaration,now if we consider this, the net force will be equal to zero. but i am still confused,am i right?
