An Asteroid of Mass 58,000 Kg Carrying a Negative Charge $15 \mu \mathrm { C }$

Multiple Choice

An asteroid of mass 58,000 kg carrying a negative charge of $15 \mu \mathrm { C }$ is $180 \mathrm {~m}$ from a second asteroid of mass $52,000 \mathrm {~kg}$ carrying a negative charge of $11 \mu \mathrm { C } .$ 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
