Grade 10Physical Chemistry
A rope ladder with a length l carrying a man with a mass m at its end is attached to the basket of a balloon with a mass M. The entire system is in equilibrium with the air. As the man climbs up the ladder into the balloon, the balloon descends by a height h. Then the potential energy of the man(1) increases by mg (l – h) (2) increases by mgh(3) increases by mgh(4) increases by mg (2l – h)
