    Gravitational field strength, E = Fg/m [ it is numerically equal to acceleration due to gravity, but conceptually it is a different quantity ] E = G*Me/(R+h)^2 Now, substitute the values.

    graviational field strength is the force experienced by a test mass which is infinitely small the test mass being considered of unit magnitude
