16) The highest value of escape velocity in the solar system is for planet: (Work, Power & Energy, escape velocity)
Correct answer: C. Jupiter
- A. Earth
- B. Neptune
- C. Jupiter
- D. Moon
Explanation
Correct Answer: (c) JupiterExplanation: Escape velocity is the minimum speed needed for an object to escape a planet's gravitational pull. It depends on the planet's mass and radius. Jupiter, with its massive size, has the highest escape velocity in the solar system at approximately 60 km/s, significantly higher than other planets like Earth (11.2 km/s) or Neptune (23.6 km/s). Incorrect Options:(a) Earth: Earth's escape velocity is much lower than Jupiter's.(b) Neptune: While Neptune has a higher escape velocity than Earth, it's still significantly lower than Jupiter's.(d) Moon: The Moon's escape velocity is even lower than Earth's due to its smaller mass.

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
