Q: In a region of space where the electric field is uniform, what is the electric flux through a surface area A oriented perpendicular to the field?
Solution: The electric flux Φ through a surface area A in a uniform electric field E is given by Φ = EA when the surface is perpendicular to the field.
Steps: 6
Step 1: Understand what electric flux is. Electric flux (Φ) measures how much electric field passes through a surface.
Step 2: Identify the uniform electric field (E). This means the strength and direction of the electric field are the same everywhere in that region.
Step 3: Recognize the surface area (A) you are considering. This is the flat area through which the electric field is passing.
Step 4: Note that the surface is oriented perpendicular to the electric field. This means the surface is facing directly into the electric field.
Step 5: Use the formula for electric flux when the surface is perpendicular to the field: Φ = EA.
Step 6: Calculate the electric flux by multiplying the electric field strength (E) by the area (A).
