The potential difference between a cloud and the Earth is `10^(7) V`. Calculate the amount of energy dissipated when the charge of `100 C` is transferred from the cloud to the ground due to lighting bolt.

Options

A. zero
B. `10^7 J`
C. `10^9 J`
D. `10^5 J`

Answer

C

Explanation

Here, `q = 100 C`
Potential difference between difference between cloud and the earth `V = 10^(7) V`
Energy dissipated `W = qV = 100xx10^(7) = 10^(9) J`
