Question

"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."

Answer 1

Answer:

Electric force, F = $2.27\times 10^6\ N$

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 :

$F=\dfrac{kq_1q_2}{r^2}$

k is Coulomb constant

$F=\dfrac{8.98755\times 10^9\times 35^2}{(2.2\times 10^3)^2}\\\\F=2.27\times 10^6\ N$

So, the magnitude of the electric force between them is $2.27\times 10^6\ N$.
