Two coherent light sources A and B with separation `2lambda` or placed on the x-axis symmetrically about the origin. They emit light of wavelength `lambda`. Obtain the positions of maxima on a circle of large radius, lying in the x-y plane and centre at the origin.

Explanation

To solve the problem of finding the positions of maxima on a large circle in the x-y plane due to two coherent light sources A and B separated by a distance of \(2\lambda\), we can follow these steps:

### Step 1: Understand the Setup
We have two coherent light sources A and B placed symmetrically about the origin on the x-axis, with a separation of \(2\lambda\). The light emitted has a wavelength of \(\lambda\). We need to find the positions of maxima on a large circle centered at the origin.

### Step 2: Define the Geometry
Let the positions of the sources be:
- Source A at \((- \lambda, 0)\)
