Because There you can fill particles in two different ways For 4e, 2 p in 2e and 1p in 0e , 1p in 2e and 2 p in 1e Simila....y for 3e, 1 p in 2e and 1p in 1e and 1p in 0e , 3 p in 1e
No. For the first excites state one fermion from E0 will be transferred to E1 making the system energy to 9E0. If one fermion is transferred from E1 to E2 the system energy will be 11E0 and it's higher than 9E0 so not the first excited state
43:33 sir hum ne particle excite kyu kiya question mai kahan bola hai
Ans: 24(π²hcut²/2mL²)
why are we taking a as 4E and b as 0E twice ? we have taken it two times. 27:43 5th row and 7th row same. 3rd row and 8th row also same

For 4e, 2 p in 2e and 1p in 0e
, 1p in 2e and 2 p in 1e
Simila....y for 3e, 1 p in 2e and 1p in 1e and 1p in 0e
, 3 p in 1e
In first qn why is gi taken as 3 .isn't it degeneracy?
Jam level questions 😅
Hari kripa
43:25 then answer should be 6 & 11
Same

Yes, you are right.

Thankyou sir
