In the figure, a cord runs around two massless, frictionless pulleys; a canister with mass m = 25 kg hangs from one pulley; and you exert a force F on the free end of the cord. What must be the magnitude of F if you are to lift the canister at a constant speed?(adsbygoogle = window.adsbygoogle || []).push({});

Here i know that the answer is mg*d. So 25*9.81*0.066m but i am not getting the answer. as i have in the book. in the previous question was To lift the canister by 3.3 cm i had to lift it by 6.6 cm so i dont what i am doing that i s wrong. Thanks for the help
