**Video Title:** Coulomb's Law Explained in 60 Seconds | NEET Physics **Video Style:** Animated educational explainer, 9:16 vertical format, engaging physics animations, professional Indian English voiceover, dynamic subtitles, and clear formulas. Target audience: Class 11 and 12 NEET aspirants. **Scene 1 (0–5 seconds) – Hook** Ever wondered why electric charges attract or repel each other without touching? Let's master Coulomb's Law in just 60 seconds! Visual: Two positive charges repel, while positive and negative charges attract. Use glowing particles and animated force arrows. **Scene 2 (5–20 seconds) – Concept** Coulomb's Law explains the electrostatic force between two stationary point charges. The force increases when the charges increase and decreases as the distance between them increases. Visual: Two charges separated by distance r. Animate the force changing as the charges move closer and farther apart. **Scene 3 (20–35 seconds) – Formula** Here's the formula: F equals k times the magnitude of q one multiplied by q two, divided by r squared. In vacuum, k is approximately nine times ten to the power of nine. Visual: Display F = k|q₁q₂|/r² with each term highlighted as it is explained. **Scene 4 (35–50 seconds) – NEET Shortcut** Remember this NEET trick! Double the distance, and force becomes one-fourth. Triple the distance, and force becomes one-ninth. Double both charges, and force becomes four times stronger! Visual: Show 2r → F/4, 3r → F/9 and (2q₁, 2q₂) → 4F. **Scene 5 (50–57 seconds) – MCQ Challenge** Quick NEET question! If the distance between two charges doubles, what happens to the force? A. Doubles B. Halves C. Becomes one-fourth D. Becomes four times Correct answer: C! One-fourth. Visual: Display four options and highlight C with a green tick. **Scene 6 (57–60 seconds) – Branding** Master NEET Physics, one MCQ at a time! Practice more on the Krita NEET JEE App! Visual: Display the Krita NEET JEE App logo with Google Play and App Store download icons.

If you double the distance between two charges, does the force become half as strong? Not quite. Coulomb's Law gives the electrostatic force between two stationary point charges. Like charges repel; unlike charges attract. The formula gives magnitude; the signs give direction. F = k|q1q2|/r2. Force grows with either charge, but falls with the square of separation. In vacuum, k is approximately 9 × 109 N·m2/C2. Now the exam shortcut: double r, and force becomes F/4. Triple r, F/9. Double both charges, and force becomes 4F. That's the turn: the formula becomes a rapid NEET shortcut. Quick MCQ: if distance doubles, is the force double, half, one-fourth, or four times? Correct answer: one-fourth. Practise more on the Krita NEET JEE App. So no-doubling distance makes force one-fourth, because Coulomb's Law follows an inverse-square relationship.
