Question

True or false the escape velocity of a body from the Earth surface Vesc to 2 under root g upon r

Answer 1

Answer:

false

Explanation:

according to MGH law and the force of attraction towards the earth crust is m=mass of body,g=9.8and h=height

Answer 2

The given statement is false.

Explanation:

The escape velocity of a body is given by :

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

Here,

G is the universal gravitational constant

M is the mass of the body

R is the radius of the astronomical body

In the given statement, the escape velocity of a body from the Earth surface is, $v_{esc}=2\sqrt{\dfrac{G}{r}}$. It is false. Hence, this is required solution.
