(20 10? Nanning) As shown in the figure, a heavy transport helicopter lifted a cargo with a mass of 9× 103Kg through a steel cable during the disaster relief mission.
Given the cargo quality, the cargo gravity is g = mg = 9×103kg×10n/kg = 9×104n, so option A is wrong and option B is correct;
Because the direction of gravity is always vertical downward, both C and D options are wrong.
So choose B.
