Question

the gravitational field intensity at a point 10000 km from the centre of the Earth is 4.8 Newton kg calculate the gravitational potential at that point

Answer 1

here is your answer

Answer 2

Answer:

The potential at that point is  $-4.8\times 10^{-7}\ Nm/kg$

Explanation:

The gravitational intensity at a point A is E=4.8 N/kg

The distance of the point A from the reference is $R=10000 km=10^{7} m$

The formulation of the gravitational intensity is

$E=\dfrac{Gm}{R^2}$              (1)

The gravitational potential is

$V=-\dfrac{Gm}{R}$                    (2)

Dividing equation 2 to 1 we get,

$\dfrac{V}{E}=-R\\V=-ER\\V=-4.8\times 10^{-7}\ Nm/kg$
