True, False, Greater than, Less Than, 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\'.

Solution

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

2. The magnitude of force on S at \'5\' is less than at \'1\'.

3. False:S has a minimum speed at \'4\'.

4. TRUE:The PE of S varies with position, depends on R.

5. The total PE+KE at \'2\' is equal to that at \'6\'.

6. True: For the orbit of S shown, P could be located at X.

7. The speed of S at \'1\' is same as that at \'7\'
