The chapter focuses on the behavior of stationary electric charges. In NEET, you can expect 2–3 direct questions from this section, ranging from basic Coulomb’s Law applications to complex Gauss’s Law flux calculations. Key Concepts to Master

Use Dimensional Analysis: Sometimes, you can eliminate two out of four options just by checking the units.

Memorize Constants: Keep the value of 1/4πε₀ (9 × 10^9 Nm²/C²) and the charge of an electron (1.6 × 10⁻¹⁹ C) on your fingertips.
