Define escape velocity

What is the escape velocity from a black hole ?

"The value of the escape velocity v_e for a stationary body on the surface of a planet is directly proportional to the mass and the radius of the planet”. Is this statement true? If not, correct it and write it.

Explain escape energy of body lying on the earth

Derive the expression of escape velocity (esape speed) of a stationary body on the surface of earth.

The earth is assumed to be a sphere of radius R. A platform is arranged at a height R from the surface of the earth. The escape velocity of a body from this platform is fu, where v is its escape velocity from the surface of the earth the value of f is ..........
