| 4. | For a satellite escape velocity from the earth is 11.2 km/s. If a body is to be projected in a direction making an angle 45° to the vertical, then what is the escape velocity? | |
| A. | 11.2×2km/s | |
| B. | 11.2km/s | |
| C. | 11.2×√2km/s | |
| D. | 11.2/√2km/s | |
| Answer: Option B | |
| Explanation: | |
|
Escape velocity does not depend on the angle of the projection of the body from the earth’s surface. Therefore v = 11.2 km/s. |
