Electric charge is uniformly distributed along a long straight wire of radius 1 mm. The charge per cm length of the wire is Q coulomb. Another cylindrical surface of radius 50 cm and length 1 m symmetrically encloses the wire as shown in the figure. The total electric flux passing through the cylindrical surface is

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 B. In this specific setup, apply the calculation to: Electric charge is uniformly distributed along a long straight wire of radius 1 mm. The charge per cm len.
