In a thundercloud there may be an electric
charge of 46 C near the top of the cloud and
−46 C near the bottom of the cloud.
If these charges are separated by about
6 km, what is the magnitude of the electric
force between these two sets of charges?
The value of the electric force constant is
8.98755 × 109 N · m2
