contrast the force of gravity between these pairs of objects: 1-kg mass and a 2-kg mass that are 1 m apart; a 1-kg mass and a 2-kg mass that are 2 m apart; and two 2=kg masses that are 1 m apart. helpppppp i dont understand.

Answer :

force of gravitation between two different masses is given by

[tex]F = \frac{Gm_1m_2}{r^2}[/tex]

here in first case we will have

[tex]F_1 = \frac{G(1kg)(2kg)}{(1m)^2}[/tex]

[tex]F_1 = 2G [/tex]Newton

another case we have

[tex]F_2 = \frac{G(1kg)(2kg)}{(2m)^2}[/tex]

[tex]F_2 = \frac{G}{2} [/tex]Newton

another case we have

[tex]F_3 =\frac{G(2kg)(2kg)}{(1m)^2}[/tex]

[tex]F_3 = 4G [/tex]Newton

so the force will be maximum in last case when two 2 kg mass is placed at 1 m distance and minimum force is in second case when 1kg and 2kg mass is placed at 2 m distance
