Question

1. What is the gravitational force of attraction between two people one of the mass
50kg and the other 70kg if they are 1.5 apart ?

Answer 1

Explanation:

we have to use Newton's formula of gravitation..

that is...

F=G×Mm/r²

you have not given the unit of the distance....I am taking it in metre

therefore...the answer comes as..

F=1555.5 ×6.67× 10^-11 N

or, F= 10.375 ×10^-8 N

hope it helps
