Define the term escape velocity. Derive expression for escape velocity of a body from
the surface of earth.
Answers
Answer:
Escape velocity: -The minimum speed with which a body must be projected. in order that it will escape from the earth gravitational filed is called as. escape velocity. Expression of it:-consider a body of mass m on the surface of earth. whose mass and radius are respectively represented by M and R.

Escape velocity is the minimum velocity required by a body to be projected to overcome the gravitational pull of the earth. ... An object that has this velocity at the earth's surface will totally escape the earth's gravitational field ignoring the losses due to the atmosphere.
The sun is 3×105 times heavier than the earth and is at a distance 2. 5×104 times larger than the radius of the earth. The escape velocity from earths gravitational field is Vc=11. 2kms−1 .
