NEET Physics Electric Field Lines Match the Following Question
Match the Column I (electric lines of force) with Column II (types of charge) and select the correct answer from the codes given below.
(A⁻p), (B⁻q), (C⁻r), (D⁻s)
(A⁻r), (B⁻q), (C⁻p), (D⁻s)
(A⁻r), (B⁻s), (C⁻p), (D⁻q)
(A⁻r), (B⁻s), (C⁻q), (D⁻p)
Correct Answer
Detailed Explanation
⚡ NEET Explanation — Electric Field Lines
Key rule 🧠
- 🟢 Field lines emerge from + charge
- 🔴 Field lines enter − charge
- Uniform spacing → uniform field-line density
- Unequal spacing → non-uniform field-line density
| Diagram | Observation | Type |
|---|---|---|
| A | Lines move outward + equally spaced | 🟢 (p) Positive, uniform density |
| B | Lines move outward + unequal spacing | 🟢 (q) Positive, non-uniform density |
| C | Lines move inward + equally spaced | 🔴 (r) Negative, uniform density |
| D | Lines move inward + unequal spacing | 🔴 (s) Negative, non-uniform density |
✅ Correct Matching
A → p, B → q, C → r, D → s
🧠 Quick Revision Trick
“OUT = +, IN = −” Equal gaps = Uniform | Changing gaps = Non-uniform
NEET Tip: Direction of arrow tells the sign of charge, while spacing/density of field lines tells about the strength/uniformity of electric field.
