| 4. | If gravitational constant is decreasing with time, what will remain unchanged in case of a satellite orbiting around the earth? | |
| A. | Time period | |
| B. | Orbiting radius | |
| C. | Areal velocity | |
| D. | Angular velocity | |
| Answer: Option C | |
| Explanation: | |
|
The central gravitational force decreases which does not exert any torque. Hence the angular momentum and consequently areal velocity remain unchanged. |
