The gravitational force after the separation between the two particles is tripled will be \boxed{\frac{{{f_0}}}{9}} .

Further Explanation:

The force of attraction due to gravity is the force which exists between two bodies kept at a distance from each other. This force is given by Newton’s law of gravitation.

The Newton’s law of gravitation states that the gravitational force of attraction between the bodies kept at a certain distance is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

The above explanation can be shown mathematically as:

\begin{aligned}F&\propto\frac{1}{{{r^2}}}\hfill\\\frac{{{F_2}}}{{{F_1}}}&=\frac{{r_1^2}}{{r_2^2}}\hfill\\\end{aligned}

The proportionality equations can be combined and the formula for the Gravitational force of attraction can be written as:

F=\frac{{G{m_1}{m_2}}}{{{r^2}}}

Let us consider that in initial distance between the two bodies is r . Now, if the distance between the two bodies is tripled of its initial distance, then the new separation becomes 3r.

Substitute {f_0}  for {F_1} , {f_1}  for {F_2} , r for {r_1}  and 3r  for {r_2}  in above expression.

\begin{aligned}\frac{{{f_1}}}{{{f_0}}}&=\frac{{{r^2}}}{{{{\left({3r}\right)}^2}}}\hfill\\{f_1}&=\frac{{{f_0}}}{9}\hfill\\\end{aligned}

Thus, the new gravitational force of attraction after increasing the separation between the two particles is \boxed{\frac{{{f_0}}}{9}} .

 <span>as i recall, gravity is relative to the square of the distance. 

so if the distance is tripled, then the gravitational attraction would be reduced by 3^2 or 1/9. 
so F1 = F0/9 


if the satellite is 2R from the center, and is moved to 4R (doubled would be 3R, tripled is 4R) then the distance is twice, and gravity would be 2^2 or 1/4.

Using the given equation you get:

E = 1.99x10^-25 / 9.0x10^-6

Divide 1.99 by 9.0: 1.99/9.0 = 0.22

For the scientific notation, when dividing subtract the two exponents:

25 -6 = 19

So you now have 0.22 x 10^-19

Now you need to change the 0.22 to be in scientific notation form:

2.2 x 10^-20

The answer is B.

How do Air molecules enable sound to travel from a radios speaker to your ears?
MatroZZZ [7]
The radio frequencies push one air molecule that then bumps into a different air molecule.....which then hits another and another causing a line of crashing molecules that lead inside your ear and hits your ear drum causing it to vibrate which causes the sounds.
