## Homework Statement

[/B]

Calculate the gravitational potential energy of the interacting pair of the Earth and a 23kg block sitting on the surface of the Earth. You would need to supply the absolute value of this result to move the block to a location very far from the Earth

(actually, you would need to use even more energy than this due to the gravitational potential energy associated with the Sun-block interacting pair).

## Homework Equations

U=-G(m1*m2)/r[/B]

## The Attempt at a Solution

G=6.67*10^(-11)

(radius of the earth)r=6.378*10^6 m

(mass of the earth)m2=5.97*10^24 kg

m1= 23 kg (as the question)

U = (6.67E-11 * 23 * 5.97E24)/6.378E6 = 1,435,963,782

This was incorrect, any help would be appreciated, thanks!
