What is the acceleration of gravity, in m/s2, on the surface (or outer limit) of Venus? The mass of Venus is 4.87 1024 kg and its radius is 6.05 106 m.

8.9 m/

Explanation:

From Newton's law of universal gravitation,

F = .............. 1

and from Newton's second law of motion,

F = mg ........... 2

Equating the two expression,

mg =

g =

Given that: mass of Venus = 4.87 x Kg, radius = 6.05 x and G = 6.67 x N

Thus;

g =

  =

 = 8.87450

g = 8.9 m/

the acceleration of gravity on the surface of Venus is 8.9 m/.

i cant see the choices man
