Answer:
F = G M m / R^2 where R is distance from center of earth
F2 / F1 = (R1 / R2)^2 equating force at R2 to force at R1 (the problem is not too clear - will assume that force at R2 is 9.1E4 N/m^2
R2 = (6.37E6 + .091E6) m = 6.46E6
R1 = 6.37E6 m
(R2 / R1)^2 = 1.03
F2 = 1 / 1.03 * 9.1E4 = 8.85E4 N gravitational force on telescope
E = F / m = 8.85E4 / 1.1E4 = 8.04 N/kg
