A charge is placed on an insulated conductor in the form of a perfect cube. What will be the relative charge density at various points on the cube (surface , edges, corners ), what will happen to the charge if the cube is in air?

Explanation

### Step-by-Step Solution:

1. **Understanding Charge Distribution on a Conductor:**
- When a charge is placed on an insulated conductor, it distributes itself on the surface of the conductor. The distribution is influenced by the geometry of the conductor.

2. **Analyzing the Cube Geometry:**
- The cube has flat surfaces, edges, and corners. The curvature at these locations is different:
- **Flat Surfaces:** The radius of curvature is infinite (flat surface).
