An asteroid of mass 58,000 kg carrying a negative charge of 15 μC is 180 m from a second asteroid of mass 52,000 kg carrying a negative charge of 11 μC. What is the magnitude of the net force the asteroids exert upon each other, assuming we can treat them as point particles? (G = 6.67 × 10-11 N ∙ m2/kg2, k = 1/4 πε0 = 8.99 × 109 N ∙ m2/C2)
