Velocity of escape is equal to
A)r × √(2g); where r: radius of Earth or any other planet for that matter, g: gravitational field strength
B)g × √(2r); where r: radius of Earth or any other planet for that matter, g: gravitational field strength
C)√(2g) ⁄ r; where r: radius of Earth or any other planet for that matter, g: gravitational field strength
D)√(2gr); where r: radius of Earth or any other planet for that matter, g: gravitational field strength

Question

Quizplus · Accepted Answer

The formula for escape velocity is derived from the conservation of energy principle and is given by $v = \sqrt{2gr}$, where $g$ is the acceleration due to gravity and $r$ is the radius of the Earth or any other celestial body.
