Question

what is the magnitude of the gravitational force of attraction between two 0.425 kilogram soccer balls when the distance between their center is 0.500 meter?

Answer 1

hope this helps.......

Answer 2

We have use the below equation to find the gravitational force (F),

$F=Gm_{1} m_{2} /r^{2}$

G - Universal Gravitational Constant

$m_{1},m_{2}$ - mass of soccer ball

r - Distance between two soccer balls

Here I will use $6.67408 X 10^{-11} m^{3}Kg^{-1}s^{-2}$ as the value for G.

Then,

$F=6.67408 X 10^{-11} X 0.425 X0.425X 10^{6}/0.5^{2}\\ \\F=4.82 X 10^{-5} N$
