An infinite number of charges, each of coulomb, are placed along x-axis at `x = 1m, 3m, 9m` and so on. Calculate the electric field at the point x = 0 due to these charges if all the charges are of the same sign.

Explanation

To calculate the electric field at the point \( x = 0 \) due to an infinite number of charges placed along the x-axis at positions \( x = 1m, 3m, 9m, \ldots \), we can follow these steps:

### Step 1: Identify the positions of the charges
The charges are placed at:
- \( x_1 = 1m \)
- \( x_2 = 3m \)
- \( x_3 = 9m \)
- and so on.
