Question

the escape velocity of a body from the Earth surface=2gm r true or false​

Answer 1

Answer:

IDK

Explanation:

Answer 2

The escape velocity of a body from the Earth surface is $v=\sqrt{\dfrac{2GM}{R}}$

Explanation:

The escape velocity of a body is defined as the velocity with which the body come out from the gravitational field. The escape velocity is given by :

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

Here,

G is the universal gravitational constant

M is the mass of the astronomical body

R is the distance between centers

So, the escape velocity of a body from the Earth surface=2gm r is not true. Hence, this is the required solution.
