Answer will be : True, False, Geater Than, Less Than, or Equal To

The path of a very small satellite S in an elliptical orbit around a massive spherical planet P is shown in the figure. The distance from 3 to 4 is the same as from 4 to 5, 9 to 10, and 10 to 11. The angular momentum of S is constant The magnitude of the force on S at '5' is... at '1' S has a minimum speed at '4' The PE of S is constant. The total PE + KE at '2' is.... at '6'. For the orbit of S shown, P could be located at X. The speed at S at position '1' is... at '7'.

Explanation / Answer

The magnitude of the force on S at `5' is .... at `1'.

Greater than

S has a minimum speed at 4

true

The PE of S is constant

False [ as the satellite's distance from the planet varies,its speed varies]

The total PE + KE at 2 is ... at 6

Equal [ total mechanical energy is always the same]

For the orbit of S shown P could be located at x

True

The speed at S at position 1 is ... at 7

equal [ speeds are the same]
