Objects with masses of 127 kg and 467 kg are separated by a distance of 0.454 m. A 69.7 kg mass is placed midway between them. Find the magnitude of the net gravitational force exerted by the two larger masses on the 69.7 kg mass. The value of the universal gravitational constant is 6.672×10⁻¹¹N⋅m²/kg². Provide your answer in units of N.
