- Object: To determine the value of e/m of electron by J.J. Thomson’s method.
In this video, we determine the specific charge value (e/m) by JJ Thomson method in hindi.
Cathode ray tube (CRT) is the main component of this experiment. As you know cathode ray tube has three components, first is electron gun, second is deflector plates for horizontal and vertical deflection and the third part is a fluorescent screen. The electron gun comprises a filament which on heating provide thermal energy to the cathode. As a result, electron emits from the cathode surface which further moves towards the anode, the potential difference between the cathode and anode decide the kinetic energy. The deflecting plates are connected with the positive terminal horizontally and vertically. So providing the potential to these plates, one can deflect the beam in any direction. In 1897, the mass-to-charge ratio of the electron was first measured by J. J. Thomson. By doing this, he showed that the electron was in fact a particle with a mass and a charge, and that its mass-to-charge ratio was much smaller than that of the hydrogen ion H+.

I couldn't understand this but after watching this video I am able to explain others thanks bro
Welcome, Your appreciation means a lot.....please subscribe and share 😊
May your subscribers increase day by day best wishes for you keep it up
Super explanation sir. This video given me complete information about the calculation of e/m value. Thank so much sir.
Welcome.....Please subscribe and share 🙂
Nice and understable presentation 🔥🔥
Thanks......Please subscribe and share 🙂
Well done. Really glad that you showed how to take the readings, really helpful. 👏
Thanku.....please subscribe and share 🙂
Sirrrrrr thanks a lot your video did what many professors couldn't
Welcome.....please subscribe and share 😊
thank you sir. mere college mein to apparatus hi nahi hai. wo exam ke din layenge bole hein. ab thoda idea ho gaya hai
Welcome and all the best for your exams👍🏻
Watching a night ago the practice exam thank you sooo much sir
Welcome....and all the best for your exams 👍🏻
Good and highly helpful dear sir. But when the angles are in 70 degree range can we do it. Please do videos related to physics and electronics.Thank you
Thanks.....please subscribe and share 😊
Very helpful …. Really wonderful explanation. ….. amazing …. Thanks u sooo much

Very nice explanation ❤
Thanku.....please subscribe and share 😊
Sir ek bat batayenge please🙏 saare value cgs mein agar rakhna hai to voltage statvolt mein rahkana padhega na?
Your question is good but unfortunately I don't have answer of this.....sorry 😔
Ok sir
Good explanation. Can you please share the data tables or related PDF?
Thanku Ma'am.....the data is confidential.
Not about the data, I am talking about theory, tables and calculation procedure, if it is possible.
@@subarnarekhabhattacharyya1961 ok.....you can take screen shots of whole manual at the end of the video.
Thanks a lot sir you have explained clearly.
Welcome.....Please subscribe and share 🙂
Very very nice sir, please upload other experiments videos
Thanks....please subscribe and check this playlist of physics practicals 👇🏻

Thank You So Soo Much Sir❤❤🙏🙏
Welcome.....Please subscribe and share 🙂
what is the use of 'Distance between magnetic poles"?? thank you
To find applied Magnetic field, if position of bar magnets were disturbed.
Awesome explanation, thanks sir.
Welcome.....Please subscribe and share 😊
Fabulous 😁😁......thank you for this beautiful explanation ❣️❣️
Welcome.....Please subscribe and share 😊
Sir bar magnet ki position same distance per honi chaiye ya different distance per bhi rakh sakte hai?
Approximately same distance hona chahiye.
Mujhe bhi aisa laga kyunki agar same distance per nahin hongi to applied magnetic field to nullify electric field won't be accurate.
Aur answer me error badh jayega.
Nyc explained sir

Sir I want the derivation of formula
Please ask to your theory teacher.
really helpfull

Magnet distance Kiya Kam korye hum
To cancel out the effect of increased electric field, we need more intensity of magnetic field which can only be obtained by decreasing the distance between bar magnets.
Any AOTians here?😂
JUlian(jadavpur university)
AOTian here...physics prac exam on 8th 😂😂
Aotian bhai ami 😂 Me department
Arey .. 😂😂😂😂
Cse vai... 8 th February exam
10^7 kaise ayaa?
In theory, at the time of formula derivation, factor 10⁷ comes for cgs unit ie emu/g or factor 10¹¹ comes for SI unit ie Coulomb/kg.
Explain in English medium sir
It's helpful for South Indians.
Thanks for the suggestion.....I added english subtitles, hope it would be helpful 👍🏻
@@RohitGuptaPhysics no meaning of subtitles 😂
@@rambaburambabu6643 yes, previously auto generated subtitles were not accurate but I corrected it now.....please check.
Where is the graph ?
We don't use graph here.
Pls send principle 😢
?
Exlain telugu sir
Sorry I don't know telugu😔
Captions 😂
Auto generated subtitles are not accurate, so I uploaded by myself.......Please check subtitles English (India).
