Electric Potential Energy lec-2 | CBSE 12 PHYSICS | JEE | NEET| PYQS of board exam

Welcome back to Lecture 2 of our Physics series! In this session, we dive deeper into Electric Potential Energy (U), exploring how work done by electrostatic forces translates into stored energy within a system of charges.📌 What You’ll Learn in This Lecture: Definition & Concept: Understanding how electric potential energy is stored when bringing charges from infinity. Derivation & Formula: Step-by-step derivation of the potential energy formula for a system of point charges .Work-Energy Principle: How work done by an external force versus conservative electrostatic forces relates to potential energy changes. Multiple Charge Systems: Calculating net potential energy for 2-charge, 3-charge, and $N$-charge configurations. Important Numerical Problems: Solved examples and practice problems designed for Class 12 board exams and competitive entrance tests (JEE / NEET).
