Question

(True, False, Less Than, Greater Than, Equal To)

1. The angular momentum of S is constant...

2. S has a maximum speed at '10'...

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

4. The total PE+KE at '2' is...at '8'

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

6. The PE of S is constant.

7. P could be located at X for the orbit of S shown.

The path of a very small satellite S in an elliptical orbit around a massive spherical planet P is shown in the fiqure. The distance from 3 to 4 is the same as from 4 to 5, 9 to 10, and 10 to 11. 2 3 4 9 7

Explanation / Answer

1. True (since gravitational force is a Central force in nature)

2. True (at nearest postion Potential energy is minimum while total energy is constant thus Kinetic energy is maximum)

3.Less than ( larger distance lesser force)

4.Equal to (Total energy is constant always during the motion around a conservative force)

5.Equal to (same distance , same potential energy , same kinetic energy)

6.False ( changing with change in position of S)

7. True
