I don't know why his voice has the power to cool my brain and force my brain to think as if I am eating or like that (I literally can't express the feeling, related to dopamine I can't tell)

[@spingosine1322]

Literally his voice whit this cute accent This sounds like this man is tooo too much cool to physics 😄😄

[@wdym20]

Much relatable bro ❤

[@anupritamali5985]

Thank you so much Khan Academy 😊❤️😌May this organisation flourish more and more🎉💐

[@josephboozanoickayuni2435]

It just took me 10 minutes to go through velocity selector problems,,,,,,,I appreciate 4 the explanation 🖤💯‼

[@SB_3.1415]

This is so flipping clever 🤯.

[@manvibahuguna1306]

Heartfelt gratitude! 🤗

[@KunalKaran-i2h]

Thank you❤❤😊

[@ChiramboWisdom-rb4sh]

Wooow!! this is way too great 🫂thank you very much for the video,i understood so well the concept of a velocity selector because of you!❤

[@scienceislove2014]

The intuition behind this concept.. loved it ..

[@viking1634]

you are gifted man keep going please

[@imjobless6739]

Thank you so much, sir!!!!

[@bosslovely27]

Great passion with great knowledge really satisfyl.

[@nauwwww]

Your way of explaining is amazing

[@mysteryuntold1489]

can you please explain how electric force is downwards it shoukd be rightwards acc to fleming left hand rule please explain it in 3:13

[@davinshy0143]

Very useful informations

[@HabibMohammed-mv3vd]

God bless you!

[@baldmonk171]

your explanation always makes me understand the topic

thanks sir😁

[@TANUJKUMARPandey9999]

Thanks a lot 🙏🏼

[@riddle_shorts]

Power of knowledge

[@priyachoudhary3105]

Thanku

[@scienceislove2014]

It clicked.. yay

[@baldmonk171]

can you update your playlist about electrostatics and magnetics?

[@bhavanabalaraman7359]

🤯🤯🤯🤯👏👏

[@curtis5448]

legend

[@swsaber8199]

is elctric field uniform

[@haseeb7274]

Minor doubt since the charged particle is perpendicular to the magnetic field wont it move in a citcular direction? Since it dosent I'm assuming that the ef on the charged particle dosent allow it to rotate in a complete circle, idk im confused rn

[@nauwwww]

charged particals are deflected in a circular path in a magnetic field. So when Fb dominates due to the high speed of the particle, it will be deflected. Charged particles are also deflected in a curved path because the particle accelerates in the direction of the electric force E.

[@nauwwww]

so yeah basically they are moving in circular path it's just that the plates aren't distant enough to see the full circle, I think

[@superachuth3236]

If the charge is a negative the direction of the magnetic force changes Is there is any change in the equation

[@grabbenskarve3518]

No because the electric force will also change to the opposite direction

[@tinuviel3949]

Thanks a lot :D

[@arjundan007]

But if it is negative then both force will be in same direction

[@sreejithd7517]

No, in the case given in the video, if electron is used, magnetic field be towards downwards ( from left hand rule) and electric field towards upwards. I too had this doubt.

[@saifulislam-lq3th]

Correct me if I am wrong, as I think you made a small mistake at the beginning. Instead of using the right hand rule, maybe you should be using the left hand rule. Besides, as of my knowledge, a positive electron beam from left to right indicates that current is flowing from left to right as well.

[@shikharpandey]

A "positive electron" beam??? Are you sure, wouldn't that just be a positron

[@rameshwarnarania5515]

Brother there are two rules

[@lalalanding234]

AAAAAAAAAAAAAAAAAAH THANK YOU SO MUCH

[@Habhinav-zz4jz]

Your voice is sesky as hell☠️🤍
