You are given the equation used to solve a problem:

$\frac{(6\mathrm{.}67{10}^{-11}(N)\frac{m^2}{k}{g}^2)(5\mathrm{.}98{10}^{24}(kg))(1000(kg))}{r^2}=\frac{(1000(kg))(7997\frac{m}{s}{)}^2}{r}$

Part A

Choose the correct realistic problem for which this is the correct equation.

A $1000$ kg comet falls on the earth with a speed of $7997\frac{m}{s}$ when it reaches the surface. What was the radius of its orbit?

A $1000$ kg comet falls on Saturn with a speed of $7997\frac{m}{s}$ when it reaches the surface. What was the radius of its orbit?

A $1000$ kg satellite orbits Saturn with a speed of $7997\frac{m}{s}.$ What is the radius of the orbit?

A $1000$ kg satellite orbits the earth with a speed of $7997\frac{m}{s}.$ What is the radius of the orbit?
