What is the escape speed on earth for any object?

Concept:

Escape Velocity (v): 

• The minimum velocity required to escape the gravity of the earth is called escape velocity.
• If an object is through with this speed or above, it will escape the gravity of earth and will not return back. 
• Escape velocity (ve) for a body on earth is given as 
• \(V_e = \sqrt {\frac{2GM}{R}}\)

  G is the universal gravitational constant, M is the mass of earth, R is the radius of the earth.

​Explanation:

The value of the Universal gravitational constant is G = 6.67 × 10-11 N kg-2 m2.

Mass of Earth is  M = 5.972 × 1024 kg

Radius of earth is R = 6370000 m

Putting this in the expression of escape velocity we will get the value of it around 11.2 km/s. 

So the correct option is 11.2 km/s
