The correct Answer is:
To solve the problem of matching the electric field line distributions in Column I with the charge distributions in Column II, we can analyze each option step by step. ### Step-by-Step Solution 1. **Analyze Column I - Electric Field Lines:** - **(A) Straight lines but not parallel**: This indicates a situation where electric field lines are directed outward but diverge from a point. - **(B) Straight lines but parallel**: This suggests a uniform electric field where lines are equally spaced and parallel. - **(C) Curved lines**: This indicates a scenario where the electric field lines bend, typically seen in dipoles or near charged objects. - **(D) Some regions where no lines are present**: This suggests areas where the electric field is zero, indicating no charge or a neutral region. 2. **Analyze Column II - Charge Distributions:** - **(p) Uniformly distributed charged shell**: Inside a charged shell, the electric field is zero, hence no lines are present. - **(q) Uniformly distributed charged long rod**: This creates a radial electric field that is straight and diverging, but not parallel. - **(r) Uniformly distributed infinite charged sheet**: This creates a uniform electric field, resulting in straight and parallel lines. - **(s) Electric dipole**: This produces curved electric field lines due to the opposing charges. - **(t) Any conducting material**: Depending on the shape, it can have regions with no electric field (like inside a hollow conductor). 3. **Matching the Options:** - **For (A) Straight lines but not parallel**: This matches with (p) Uniformly distributed charged shell (since inside the shell, there are no lines) and (q) Uniformly distributed charged long rod (as it has straight lines that diverge). - **For (B) Straight lines but parallel**: This matches with (r) Uniformly distributed infinite charged sheet (as it has straight and parallel lines) and (q) Uniformly distributed charged long rod (as it has straight lines). - **For (C) Curved lines**: This matches with (s) Electric dipole (as it has curved lines). - **For (D) Some regions where no lines are present**: This matches with (p) Uniformly distributed charged shell (inside the shell) and (t) Any conducting material (inside a hollow conductor). ### Final Matches: - **A** matches with **p** and **q**. - **B** matches with **q** and **r**. - **C** matches with **s**. - **D** matches with **p** and **t**. ### Summary of Matches: - A → p, q - B → q, r - C → s - D → p, t
