"In a thundercloud there may be an electric charge of 35 C near the top and −35 C near the bottom. These charges are separated by approximately 2.2 km. What is the magnitude of the electric force between them? The Coulomb constant is 8.98755 × 109 N · m2 /C 2 . Answer in units of N."

Electric force, F =

Explanation:

Given that,

In a thundercloud there may be an electric charge of 35 C near the top and −35 C near the bottom.

The separation between charges, r = 2.2 km

We need to find the magnitude of the electric force between them. We know that the formula used to find the electric force is given by :

k is Coulomb constant

So, the magnitude of the electric force between them is .
