Question no 20 .....sir aik confusion ha.... Hum shuru sa yahi prhta ay han k energy kisi bi metal pr pra gi tu electron release ho ga....ab achanak sa hma prhaya ja rha ha k jb energy act kra gi tu electron bi nikla ga aur uski bhn positron bi.,..ya accept krna thora mushkil ho jata ha mera lia..lakin jb ap khtay han k law of conservation of energy ko follow krta hoa aik electron ka sath aik positron ka nikalna zrooro ha wrna charge stable nai rha ga aik side pa ziada aik side pa km....lakin sir aghr dekha jay tu energy pr koi charge nai hota ha aur aghr electron release krwaya jay tu negative one charge a jay ga.....enegy decrease hi ho rai ha na.. increase tu nai ho rahi na jo tension lan k universe k rule sa ulta kam krdia koi....law of conservation of mass according bi tu aesa hi hota tha naa last year prha ha. K jb mass ki conversion hoti ha tu small amount of kinetic energy bi sath release hoti ha.....ma khna chah rai thi may be electron k sath bi koi thori si energy release ho jayy aurr law of conservation of energy bi follow hota rha aur electron bi aik hi bahir nikla....🤔🤔🤔🤔sir guidee meeee plzzzz wrnaa ma na physics ka murder krdena ha

[@Dani-w4h3b]

Ohh Bhai khamoshi sai Jo hai accept kro koi Naya logic na lgao yr

[@GhulamHussain-s9n7e]

Pehly energy pe koi charge ni tha mean initial momentum zero aur jb hmm heavy nucleus pe energy strike krein tu pair production ka phenomenon hta he aur electron aur positron 2no produce hote hen ta k 2no opposite direction me move krein aur aik 2sry k effect ko cancel kr de aur final momentum bhi zero ho jai aur law of conservation of momentum applicable rhe agr sirf electron produce ho tu tu final momentum zero ni hota aur ye law of conservation of momentum ki violation he

[@fatimagaming655]

Aoa sir gg your teaching method is osm🤩

[@SUBHANIMABDULBASIT]

good

[@Invideozaeem]

Sir question 5 Ka answer yes ha lakin AP na no btaya..Yes. When you compress a spring you do work on it, adding energy to it.the rest mass of a compressed spring exceeds the rest mass of an uncompressed spring.

[@physicskasafar]

Yes and no dono ho sakte hn.
Kis tarhan dono ho sakte hn
Ye kafi detail se btaya h mene video mn

[@sabaajmal6875]

Sir But In Numericals19.8 we Put value Of electron mass is 9.11 10 raise power 31nd proton has mass 1.67 10 raise power 27 ...Is mn To electron ka mass zada ha proton sy??

[@physicskasafar]

Minus mn value jitni zyada hoti h utni hi km hoti h
-27 bra h
-31 choota h

[@najeebsultan8249]

Sir jis traaaa ap NY 20 que btaya k hum photon sy single electron nai generate kr sakty
Que k law of conservation of charge ki violation hotiii h
But sir Photo electric effect m tou single electron heeee emit hota h naaaa
Yahan py b violate hogaaaa na?

[@physicskasafar]

Wahan pr emit hota h Jo metal mn pehle se hi mojud h
Yahan pe photon quantum mechanically change hota h electron aur positron mn
Wahan pr emit hota yahan pr generate hota

Sir book mayn 17 question ka answer 2 hai how?

[@nadeemashraf2957]

sir aap ne to kaha tha ke no of photon frequency and energy pe depend nahi karta or hum visible light ki intensity barha kar ye phenomena nahi kar sakte? please replyyyyyyyyyyyy

[@physicskasafar]

Number of electron Jo emit ho re hain metal surface se wo photon ki frequency aur energy pe depend Ni karte.
Matlab hm photon ki frequency aur energy ko increase kr k number of electron ko nai barha sakte
Number of electron barhane k liye hamain number of photons ko increase Karna pare ga

[@nadeemashraf2957]

thank you sir.
