Coulomb's Law: An asteroid of mass 58,000 kg carrying a negative charge of 15 ?C is 180 m from a second asteroid of mass 52,000 kg carrying a negative charge of 11 ?C. 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 ??0 = 8.99 × 109 N ? m2/C2)
A. 0.000040 N
B. 0.0062 N
C. 570,000 N
D. 510,000 N
