XII Physics 2025 Two point charges + q and - q are held at (a, 0) and (- a, 0) in x-y plane

(i) Two point charges + q and - q are held at (a, 0) and (- a, 0) in x-y plane. Obtain an expression for the net electric field due to the charges at a point (0, y). Hence, find electric field at a far off point (y 》a). (ii) Three point charges of - 2 nC, - 1 nC, and + 5 nC are kept at the vertices A, B and C of an equilateral triangle of side 0.2 m. Find the total amount of work done in shifting the charges from A to A1, B to B1, and C to C1. Here A1, B1, and C1 are the midpoints of sides AB, BC and CA, respectively. 12th Physics CBSE PYQ 2025 CBSE 12th Physics Solution Class 12th CBSE Physics Class XII CBSE Physics CBSE 12th PYQ 2025 Physics CBSE 12th PYQ 2024 Physics CBSE with PYQ 2023 2025 Physics 12th PYQ CBSE Solution Physics 12th CBSE sample paper solution Physics Class 12th CBSE Physics Previous year questions solution Class 12th CBSE Physics Previous year questions solution CBSE Maths 12th PYQ Solution Physics #cbseboard #cbse #cbseclass12 #maths #physics #study #boardexam #class12th #examination #education #science #physics
