The diagram shows a thundercloud whose base is 500 m above the ground. [Figure 31.1] The potential difference between the base of the cloud and the ground is 200 MV. A raindrop with a charge of 4.0 × 10⁻¹² C is in the region between the cloud and the ground. What is the electrical force on the raindrop?
