### Educational Website Transcription---#### Problem 3**Description:**A hollow copper spherical shell with an inner radius \( a = 2 \, \text{cm} \) and an outer radius \( b = 3 \, \text{cm} \) carries a charge of \(- 1.6 \, \mu \text{C}\). At the center of the sphere, there is a positive point charge of \( +10 \, \mu \text{C} \). Find an expression for the electric field \( E(r) \) in the three regions I, II, and III, where \( r \) is the distance from the center. Include the direction in your answers.**Diagram Explained:** The diagram features a cross-sectional view of the spherical shell divided into three labeled regions. - Region I is within the inner radius \( (r < a) \).- Region II is between the inner and outer radii \( (a < r < b) \).- Region III is outside the outer radius \( (r > b) \).Arrows point radially outward from the center, indicating the direction of the electric field.---#### Problem 4**Description:**- **Part a:** The point charge is at the center of a cube. The cube has sides of \( 1 \, \text{cm} \) and \( 1.5 \, \text{cm} \). Find first the electric flux through the side of the cube that is facing a cone, and then the total flux through the cone with a height of \( 2 \, \text{cm} \) and radius \( 0.8 \, \text{cm} \). **Diagram Explained:** A cube with a point charge \( +10 \, \mu \text{C} \) at its center adjacent to a cone is illustrated. The dimensions of the cube's side (\( 1 \, \text{cm} \) and \( 1.5 \, \text{cm} \)) and the cone's height (\( 2 \, \text{cm} \)) and base radius (\( 0.8 \, \text{cm} \)) are provided.- **Part b:** Remove the cube and the point charge. Assume now there is a uniform vertical electric field \( E =
