Question

derive an expression for escape velocity of a body ​

Answer 1

Answer:

Derivation of Escape Velocity

Derivation of Escape Velocity:

Escape Velocity Formula:

v_{e}=\sqrt{2gR}

Derivation:

v_{e}

Now, the work done against the gravitational attraction to take the body from the planet's surface to infinity can be easily calculated by integrating the equation for work done within the limits x=R to x=∞.

K.E. = W.
