Q5. How much the escape velocity from earth?
Ans. 
Escape velocity from Earth is approximately 11.2 km/s.
• Escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a planet.

• It is calculated using the formula: escape velocity = sqrt(2 * gravitational constant * mass of the planet / radius of the planet)

• For Earth, the escape velocity is approximately 11.2 km/s.

• Escape velocity varies depending on the planet's mass and radi
