Question

Using the law of conservation of energy, derive the
expression for the escape velocity of an object from the
Surface of the earth.​

Answer 1

Answer:

Answer: It is the minimum Velocity with which a body should be projected from the surface of the planet so as to reach infinity . KE + PE at surface of planet = KE + PE at infinity . ... If we put value of R and g of Earth we get Ve = 11.2 Km/s ( approx ) .
