You are given the equation used to solve a problem:

$(6\mathrm{.}671011$Nm$2/$kg$2)(5\mathrm{.}981024$kg$)(1000$kg$)$r$2=(1000$kg$)(5997$m$/$s$)2$r$(6\mathrm{.}671011$Nm$2/$kg$2)(5\mathrm{.}981024$kg$)(1000$kg$)$r$2=(1000$kg$)(5997$m$/$s$)2$r

Part A

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

A $1000$ kgkg satellite orbits the earth with a speed of $5997$ m$/$sm$/$s$.$ What is the radius of the orbit?A $1000$ kgkg satellite orbits Saturn with a speed of $5997$ m$/$sm$/$s$.$ What is the radius of the orbit?A $1000$ kgkg comet falls on Saturn with a speed of $5997$ m$/$sm$/$s $$when it reaches the surface. What was the radius of its orbit?A $1000$ kgkg comet falls on the earth with a speed of $5997$ m$/$sm$/$s $$when it reaches the surface. What was the radius of its orbit?
