1. The problem statement, all variables and given/known data 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). 2. Relevant equations U=-G(m1*m2)/r 3. 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!
