Question

If the potential difference between two parts of a thundercloud is 10⁸ V, what is the amount of energy given up during the passage of 20 coulombs?

Options

• 2 × 10⁻⁷ J

• 200 J

• 5 × 10⁶ J

• 2 × 10⁹ J

• 2 × 10¹⁰ J

Answer 1

2 × 10⁹ J

Explanation:

Given: Potential difference, \(V = 10^8\,V\)

Charge, \(Q = 20\,C\)

Formula: \[ W=VQ \].

\[ W=10^8 \times 20 \].

\[ W=2 \times 10^9 \mathrm{J} \]
