Detailed step-by-step solution for JEE Mains 2026 (24 January, Shift 2) Physics question on Capacitors and Dielectrics.

Question:
Q.29 Three parallel plate capacitors each with area A and separation d are filled with two dielectric (k1 and k2) in the following fashion. Which of the following is true? (k1 greater than k2)
[Image shows three capacitors (A), (B), and (C) with different arrangements of dielectrics k1 and k2. Each capacitor has total thickness d (split into two layers of d/2) and total length L (split into two halves of L/2).]

In this video, we break down how to calculate the equivalent capacitance for different dielectric arrangements by breaking them into smaller parts, modeling them as series and parallel combinations from first principles, and comparing their effective values to find the correct order.
