Question

Tom has a mass of 70.0kg and Sally has a mass of 50kg. Tom and Sally are standing 20.0m apart on the dance floor. Sally looks up and sees tom. She feels an attraction . if the attraction is gravitational find it's size assume that both tom and Sally can be replaced by spherical masses

Answer 1

please you have to use the Newton's formula, namely:
\[F=G \frac{ M _{T}*M _{S} }{ d ^{2} }\]
where M_T is the mass of Tom, M_S, is the mass of Sally, d is the distance between them, and G is the gravitational constant, whose value is:
\[6.673*10^{-11}\] S.I. units

Answer 2

so what is the answers

Answer 3

what is the answer

Answer 4

\[F=6.673*10^{-11}\frac{ 70*50 }{ 400 }=...\]
please complete the calculus, it's very simple

Answer 5

thanks you are so nice
