To solve the problem, we need to find the mean energy flow rate through a ring centered at point A, which is at a distance \( x \) from the isotropic point source at point O. The radius of the ring is \( R \). ### Step-by-Step Solution: 1. **Understanding Intensity**: The intensity \( I_0 \) at point A is defined as the power per unit area received from the isotropic point source. For a point source, the intensity decreases with the square of the distance from the source. 2. **Area of the Sphere**: ...
