The escape velocity from Earth's Gravitational field depends upon:
Correct answer: C. Radius of earth
- A. Rotation of earth
- B. Mass of body
- C. Radius of earth
- D. Mass of earth
Explanation
The formula for escape velocity (v) is:v = √(2GM/R)where:G is the gravitational constantM is the mass of EarthR is the radius of EarthAs you can see from the formula, the escape velocity is directly proportional to the square root of the radius of Earth (R). This means that if the radius of Earth were to increase, the escape velocity would also increase. Conversely, if the radius of Earth were to decrease, the escape velocity would decrease.

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.
