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 . Now, if the distance between the two bodies is tripled of its initial distance, then the new separation becomes .

Substitute ${f_0}$ for ${F_1}$ , ${f_1}$ for ${F_2}$ , for ${r_1}$ and 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 $\boxed{\frac{{{f_0}}}{9}}$ .

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.
