J.J. Thomson's Experiment : An electric field was applied in the path of Atomic Structure cathode rays in the discharge tube. It was observed that cathode rays were deflected towards the positive plate of the electric field. This showed that cathode rays were negatively charged. When a magnetic field was applied in the path of cathode rays, they were again deflected in a direction in which moving negative charge would be deflected,. This proved that athode rays contained negatively charged particles called electrons.
30:36 doubt. Moon toh earth ke around apni trf se koi bhi force nhi lgata ghumne ke liye. Ho skta hai electron bhi aisa hi kaam krta ho (centripetal force)
~thanxss for your best~explanation~^~😘 I'm very week in chemistry 🤕...and I also want to read and learn chemistry 😊.. So,i found u mam🥺💞 U're the inspiration of all students of this generation 💫 Once again thanxs mam💫..
Kal mera exam hai abhi raat k bara baje Maine ye 2x speed pe dekha fir bhi mujhe Saab samajh aya aur Mera exam bhi kal acha jayega thank you very much mamm❤ love from Siliguri ❤️🥺
ME reading comments in college ( free period hai ) and my friends playing game. But some comments are very bad about teacher! I suggest you pls give respect to your teacher 😎
Your understanding trick is better than all teacher. I say I yet teach everyone teacher in TH-cam but your explanation is great.. You are also a legend
Electron jo energy lose karega to atom unstable ho jaayega Lekin Atom unstable nhi stable hota hai Isiliye ye definition galt hai ... Electron apni energy ko lose nhi karta wo fixed hota hai .... I hope uhh understand If uhh don't then uhh should watch magnet brains videos bro 😊

Moon toh earth ke around apni trf se koi bhi force nhi lgata ghumne ke liye.
Ho skta hai electron bhi aisa hi kaam krta ho (centripetal force)
Gravitation force hota h

Plz reply Madam ji...?
If anyone know about this so please help me bhaiyooon😢😢
Electron jo energy lose karega to atom unstable ho jaayega
Lekin
Atom unstable nhi stable hota hai
Isiliye ye definition galt hai ...
Electron apni energy ko lose nhi karta wo fixed hota hai ....
I hope uhh understand
If uhh don't then uhh should watch magnet brains videos bro 😊
