The path of a very small satellite S in an elliptical orbit around a massive sph

Question

The path of a very small satellite S in an elliptical orbit around a massive spherical planet P is shown in the figure below. The distance from 3 to 4 is the same as from 4 to 5,9 to 10, and 10 to 11 #3 10. Select True, False, Greater than, Less than, or Equal to The torque exerted on S varies with position S has its mnim speed at 10 . Ihe KE of S varies with position. vFor the shape of the orbit S shown, P could be located at X The speed of S at position'l'is. at7". The magnitude of the force on S at '2, is at '8. , The total PF ÷ KE of S at '4' is that at 9. Problem Weight is: 1

Explanation / Answer

once the satelite enters into the orbit there is no external force acting on the system hence the torque does not varie with position (answer: false)

10 th position is very close to the P so attractive force is more to dominate this satellite should move faster (false)

yes at different positions the satellites having different velocities hence kE varies(true)

yes we can locate because ellipse having two foci we can locate at any one of the focus(true)

both are at equal distance so speed at 1 and 7 are equal.

the magnitude of force at 2 is less than at 8 becuase it is close to planet.

equal at 4th and 9th places.
