Electric Charges and Fields: NCERT Exemplar Solutions

Physics Class 12 ka ye pehla chapter bahut important hai. Ismein electric charge, Coulomb's law, electric field, dipole, aur Gauss's law jaise basic concepts par focus kiya gaya hai. NCERT Exemplar book ke questions inhi concepts ki deep understanding test karte hain.

MCQs ke Solutions aur Explanations

Chapter ke shuru mein diye gaye Multiple Choice Questions ke answers yahaan par detailed reasoning ke saath diye ja rahe hain. Har answer ko samajhna important hai kyunki ye fundamentals clear karte hain.

• Question 1.1: Electric charge quantization se related sawal. Iska answer (b) hai aur iska reason ye hai ki charge hamesha electron charge 'e' ka integral multiple hota hai.
• Question 1.2: Do charges ke beech force par sawal. Coulomb's law lagakar correct option (c) aata hai.

Short Answer Type Questions

In questions mein aapko concepts ko theoretically explain karna hota hai aur chhote numerical solve karne hote hain.

Example Solution: Electric dipole moment ki definition aur uska SI unit likhna. Electric dipole moment do equal and opposite charges ke beech ki distance aur charge ke magnitude ka product hota hai. Iska SI unit Coulomb-meter (C m) hai.

Long Answer Type aur Numerical Problems

Ye section zyada challenging hai. Ismein derivation, proof, aur complex numerical problems hote hain.

Numerical Example: Ek question mein diya gaya hai ki do point charges 2 microCoulomb aur 3 microCoulomb, vacuum mein 10 cm ki duri par rakhe hain. Unke beech lagna wala force calculate karna hai. Humein Coulomb's law formula use karna hoga: F = (1/(4πε₀)) * (q1*q2)/r². Values put karne par force aayega 5.4 N, jo ki repulsive hoga kyunki dono charges same sign ke hain.

Gauss's Law ke Applications

Chapter ka ek major part Gauss's law par hai. Exemplar questions mein aapko different shapes jaise infinite line charge, charged spherical shell, aur charged conductor ke liye electric field calculate karne ko kahenge. Har case ke liye appropriate Gaussian surface choose karna seekhna zaroori hai.

In solutions se students ko sahi method se problem solve karne ki practice milegi. Har step clearly explain kiya gaya hai taaki concept achhe se samajh mein aaye. Ye solutions CBSE board exam pattern ke hisaab se perfect hain aur last-minute revision mein kaam aayenge.
