Question

1. In Year 3,000 humans mastered to forge a new planet from materials collected in the asteroid belt between Mars and Jupiter. This new planet F has radius R_F=48,000 km. If an object is placed at an altitude h =5,200 km above the surface of Planet F, the object’s weight is the same as on the surface of the Earth. What is the gravitational acceleration g_Fs on the surface of Planet F in m/s²? (Hint: Eliminate the mass of Planet F from an equation using the fact g = g_F).
