Question

State whether the following statement is true and false The escape velocity of a body from the earth surface ,Vesc=2√GM/R

Answer 1

The given statement that the escape velocity of a body from the earth surface is $v=\sqrt{\dfrac{2GM}{r}}$ is true.

Explanation:

If an object is moving under free fall, escape velocity is the velocity an object needs to escape the gravitational influence of a body. It is given by :

$v=\sqrt{\dfrac{2GM}{r}}$

Here,

G is universal gravitational constant

M is the mass of central body

r is the distance

So, the given statement that the escape velocity of a body from the earth surface is $v=\sqrt{\dfrac{2GM}{r}}$ is true.
