The figure shows a hollow hemisphere of radius R in which two charges 3q and 5q are placed symmetrically about the centre O on the planar surface. The electric flux over the curved surface is:

Question

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: The figure shows a hollow hemisphere of radius R in which two charges 3q and 5q are placed symmetrically.
