Value of escape velocity for the surface of the earth is 11 km/sec. Its value for surface of the moon is:
Correct answer: C. 2.4 km/sec
- A. 11 km/sec
- B. 10.4 km/sec
- C. 2.4 km/sec
- D. 4.3 km/sec
Explanation
The correct answer is Option C: 2.4 km/sec. The escape velocity for the Moon is approximately 2.374 km/sec. This is significantly lower than Earth's escape velocity due to the Moon's smaller mass and gravitational pull. Options A and B are incorrect because they refer to the escape velocities of Earth and Venus, respectively. Option D is also incorrect as it does not correspond to any known celestial body's escape velocity.
