PHY-123 YCMOU Assignment Answers 2026-27

Earn 30% of your M.Sc. (Physics) marks with precision—this PHY123 Solved Assignment is your direct link to Continuous Assessment (CA) success under YCMOU’s 2022 pattern. Designed exclusively for students navigating electrodynamics and classical field theory, it eliminates guesswork by providing fully worked solutions for every Home Assignment (गृहपाठ) question—including vector potential derivations and Lorentz force calculations with rigorous dimensional checks.

Academic Objective & Curriculum Alignment

PHY123 at YCMOU is structured to deepen mastery of electromagnetic theory through core modules:

• Chapter 1: Electrostatics – Gauss’s Law applications with bound charge density analysis (Section 1.3)
• Chapter 3: Magnetostatics – Ampère’s Law derivations for solenoidal currents (Problem 3.7)
• Chapter 5: Maxwell’s Equations – Wave propagation in dielectric media (Example 5.4)

The assignment solutions directly map to these chapters, ensuring your answers align with YCMOU’s Self-Instructional Material (SIM) expectations. Each solution includes:

• Step-by-step derivations with vector notation (e.g., ∇ × E for Faraday’s Law)
• Numerical examples with SI unit consistency (e.g., Tesla, Coulomb/m²)
• Cross-references to YCMOU’s Study Centres (अभ्यास केंद्र) problem sets

Continuous Assessment & Exam Utility

This resource is non-negotiable for:

• CA Marks (30%): Solves all 10 Home Assignment (गृहपाठ) questions with YCMOU-verified answer formats, including:
• Part A (Theoretical): 5 short-answer questions on Poynting vector and displacement current (Section 2.5)
• Part B (Numerical): 5 problems with step-by-step dimensional analysis (e.g., Problem B.3: Magnetic field in a toroid)
• Term-End Exam (TEE) Preparation: Covers 90% of TEE weightage via:
• Advanced topics like relativistic electromagnetism (Chapter 6)
• YCMOU’s past TEE question patterns (e.g., 2022 TEE Question 4)
• Graphical solutions for electric field lines and magnetic flux (Figure 4.2)

Study Guidelines for YCMOU Students

Optimize your learning with these YCMOU-specific strategies:

• PRN Compatibility: Solutions align with 2022 pattern PRN codes (e.g., PHY123-101, PHY123-102)
• Study Centre (अभ्यास केंद्र) Alignment: Includes model answers for YCMOU’s weekly tutorial questions
• Time Management:
  • Dedicate 2 hours to review solutions for each Home Assignment (गृहपाठ)
  • Practice 3 numerical problems daily from the SIM workbook
• Avoid Common Pitfalls:
  • Do not copy verbatim—use solutions as a reference guide for your own derivations
  • Always cite YCMOU’s SIM in your answers (e.g.,
