G1 Physics · Accepted Answer

Step 1: Electric flux through a surface is Φ = ∫𝐄·d𝐀; for a uniform field and a plane, Φ = EA cosθ. Step 2: Determine the area vector from the given geometry and take the component of 𝐄 normal to the surface. Step 3: Multiplying the normal field component by the area gives the required flux. Final: Option D. In this specific setup, apply the calculation to: A hollow cylinder has a charge q coulomb symmetrically within it. If φ is the electric flux in units of V.
