A rope ladder of length L is attached to ballon of mass m. As the man of mass m clims the ladder in to the lballon basket the ballon comes donws by a vertical distance s. Then increase in potential energy of man divided by increase inn potentialenergy of ballon is |

Answer» `(L-s)/(s)` mg L = mg (L-s)++mg.s where .mg(L-s) = increases in P.E of man mg s = increases in P.Eof man mg s= increases in P.Eballoon so (increase in P.E of man)/(increase of P.E of BALLON)=(mg(L-s)/(mgs)` `=(L-s)/(s)` |
