Question

What is the force of gravitation between two objects,given two objects mass 15 kg and 20 kg respectively and the distant is 20m each?

Answer 1

Answer:

Given,

mass of first object (m1) = 15kg

mass of second object (m2) = 20kg

Distance between the two objects (r) = 20m

We know that,

Force(f) = G*m1*m2/r*r = 6.67*10*15*20/20*20

solve it and you'll get your answer

Answer 2

Answer:5.0025*10^-11

Explanation:

F=?

mass1=m1= 15kg

mass2=m2=20kg

distance=r=20m

The gravitational constant (G)=6.67*10^-11m^3kg^-1s^-1

therefore

F=Gm1m2/r^2

=6.67*10^-11*15*20/(20)^2

=2.001*10^-8/4*10^2

F=5.0025*10^-11 N
