The work done by the gravitational field of the earth on the rock is 9.998 x 10⁸ J.
<u>The given parameter include:</u>
the mass of the object, m₁ = 16 kg
Note: the mass of the earth, m₂ = 5.972 x 10²⁴ kg
- The work done by the gravitational field of the earth is given as;
Work done = gravitational force (F) x radius of the earth (R)
Therefore, the work done by the gravitational field of the earth on the rock is 9.998 x 10⁸ J.
