Answer:
First case : Gravitational force = 1.5625
Second case : Gravitational force = 0.04
Explanation:
a) The separation distance is four-fifths the original distance.
Distance decreases, so force increases. i .e., F2 ÷ F1
so ( [tex]\frac{5}{4}[/tex] )²
= [tex]\frac{25}{16}[/tex]
= 1.5625
b) The separation distance is 5 times the original distance. i.e. F2 ÷ F1
Distance increases, so force decreases.
so [tex]\frac{1}{5}[/tex]²
= [tex]\frac{1}{25}[/tex]
= 0.04
