Question

state whether the following statement is true or false - the escape velocity of a body from the earth surface,escape velocity=2√GM÷R
​

Answer 1

Answer:

the statement is true

Explanation:

pls mark me as brain list

Answer 2

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

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 is $\sqrt{\dfrac{2GM}{R}}$ is true. Hence, this is the required solution.
