Question

gravitational force: what is the gravitational force acting on a 59-kg person due to another 59-kg person standing 2.0 m away? we can model each person as a small sphere. (g

Answer 1

`F=5.81* 10^(-8) N(Roughly)`

Step-by-step explanation:

Given:

mass of first person
`m_1=59 kg`

mass of second person
`m_2=59kg`

distance between them
`r=2 m`

Using newtons law of gravitation, which states that: If two particles with masses
`m_1` and
`m_2` are separated by a distance r, a gravitational force F acts along a line joining them, with magnitude given by:

`F=G* (m_1* m_2)/(r^2)`

`G=6.674 * 10^(-11)(m^3)/(kg* s^2)`

by direct substitution, we can find the force exerted, which turns out to be:

`F=6.674* 10^(-11)* (59* 59)/(2^2)=5.81* 10^(-8) N` (roughly)
