To solve the problem, we need to calculate the net force experienced by a charge of \(0.1 \, C\) placed at the origin due to an infinite series of point charges of \(9 \, \mu C\) located at \(x = 1 \, m, 2 \, m, 4 \, m, 8 \, m, \ldots\). ### Step-by-Step Solution: 1. **Identify the Charges and Their Positions:** The charges are placed at positions \(x = 1 \, m, 2 \, m, 4 \, m, 8 \, m, \ldots\) which can be expressed as \(x = 2^n\) for \(n = 0, 1, 2, 3, \ldots\). Each charge has a magnitude of \(q = 9 \, \mu C = 9 \times 10^{-6} \, C\). 2. **Use Coulomb's Law to Calculate the Force:** ...
