Earlier in the chapter, we saw that tumbling sand and dust grains can develop an electric charge. Typically, smaller grains develop a negative charge, while larger grains develop a positive charge. The smaller grains tend to be lofted higher by the wind, as we’d expect, so when a strong, steady wind blows across a sandy landscape, a charge separation develops. This produces an electric field near the ground, which can reach values as high as 150,000 N/C. At this field strength, how does the magnitude of the electric force compareto the weight force for a typical dust particle of mass 1.8 × 10-12 kg and charge 1.2 × 10-16 C?
