Repost from 𝐏𝐨𝐬𝐢𝐭𝐢𝐯𝐞 𝐓𝐡𝐢𝐧𝐤𝐢𝐧𝐠 ✨
New Year not only means flip of the calendar 🗓, but it represents a clean break, a new hope, and a blank canvas.❤️
New Year means 366 new chances😍.The new year stands before us, like a chapter in a book, waiting to be written✍. We can help write that story by setting goals.💯
There is always an opportunity to start again and again, if the old ways are not working last year, look for better ways of doing it in the new year and start again afresh.😌💞
Wish you all a very happy New Year 2026.💞
May Kanha ji blesses you all with a lots of happiness and success in your life .😌❤️
🎓 The Blueprint by IIT Bombay Students: Final 30 Days to JEE Mains
Hard work alone won't improve your rank in the final month - Smart Strategy will. The difference between a 95%ile and 99%ile often comes down to knowing what to study and what to skip in the final days.
We have invited two IIT Bombay students (recent JEE Advanced Toppers) to cover:
✅ 30-Day Action Plan: A granular, day-by-day roadmap till the exam.
⚖️ Boards vs. JEE: How to balance both without compromise.
⚡️ "Cheat Topics": High-yield chapters to secure 100+ marks easily.
📝 Trend Analysis: Most repeated Qs from the last 10 years.

🗓 Date & Time: 26 December at 9 PM
Note: The joining link will be sent via email and WhatsApp only to registered students.
Electric Charges and Fields
1. Electric Charge Charge is the property associated with matter due to which it produces and experiences electric and magnetic effect.
2. Conductors and Insulators Those substances which readily allow the passage of electricity through them are called conductors, e.g. metals, the earth and those substances which offer high resistance to the passage of electricity are called insulators, e.g. plastic rod and nylon.
3. Transference of electrons is the cause of frictional electricity.
4. Additivity of Charges- Charge are scalars and they add up like real numbers. It means if a system consists of n charges q1, q2, q3 , … ,qn, then total charge of the system will be q1 +q2 + … +qn.
5. Conservation of Charge The total charge of an isolated system is always conserved, i.e. initial and final charge of the system will be same.
6. Quantisation of Charge -Charge exists in discrete amount rather than continuous value and hence, quantised.
Mathematically, charge on an object, q=±ne
where, n is an integer and e is electronic charge. When any physical quantity exists in discrete packets rather than in continuous amount, the quantity is said to be quantised. Hence, charge is quantised.
7. Units of Charge
(i) SI unit coulomb (C)
(ii) CGS system
(a) electrostatic unit, esu of charge or stat-coulomb (stat-C)
(b) electromagnetic unit, emu of charge or ab-C (ab-coulomb)
1 ab-C = 10 C, 1 C = 3 x 109 stat-C
