vishweshshrimali5 · Answer

use

g = GMm/r^2

turingtest · Answer

derive it from what, the general formula
$$F_g=Gm_1m_2/r^2$$
?
you mean F= vishweshshrimali...

vishweshshrimali5 · Answer

yes !!

sorry the correct formula is

g = GM/r^2

turingtest · Answer

think of a falling object
$$mg=Gm_em/r^2$$
the m's of the falling object cancel giving
$$g=Gm_e/r_e^2$$
Plug in the values for the constant G=6.67x10^(-11), mass of the earth, and radius of the earth and you should get 9.8m/s^2

anonymous · Answer

wahe guru what is confusion now ?

turingtest · Answer

g=(6.67e-11)(5.9742e24)/(6.378e6)^2=9.795... about 9.8m/s^2
