Expert Solution
Step 1

Given that - 

  • Radius of the earth
  • Gravitational field strength of earth at required altitude is two- third of gravitational field strength of earth's surface

To Find -

We have to calculate the altitude  above the earth's surface where gravitational field strength of earth is two- third of gravitational field strength of earth's surface.
