The drawing (not to scale) shows one alignment of the sun, earth, and moon. The gravitational force F SM that the sun exerts on the moon is perpendicular to the force F EM that the earth exerts on the moon. The masses are: mass of sun = 1.99 × 1030 kg, mass of earth = 5.98 × 1024 kg, mass of moon = 7.35 × 1022 kg. The distances shown in the drawing are rsM = 1.50 × 1011 m and rEM = 3.85 x 10° m.

The gravitational force F→SM that the sun exerts on the moon is perpendicular to the force F→EM that the earth exerts on the moon. The masses are: mass of sun = 1.99 × 1030 kg, mass of earth = 5.98 × 1024 kg, mass of moon = 7.35 × 1022 kg. The distances shown in the drawing are rSM = 1.50 × 1011 m and rEM = 3.85 × 108 m.

If an imaginary line segment is drawn between the centers of the earth and the moon, then the net gravitational force F acting on an object situated on this line segment is F = -k/x^2 + 0.012k/(239-x)^2 where K > 0 is a constant and x is the distance of the object from the center of the earth, measured in thousands of miles. How far from the center of the earth is the "dead spot" where no net gravitational force acts upon the object? (Express your answer to the nearest thousand miles. Hint: The distance from the earth to the moon is approximately 239 thousand miles.)
