Answered Feb 05, 2023
Correct Answer - `-2.304xx10^(-18) J`
Correct Answer - `n_(e)~~4.95xx10^(22);n_(h)=4.75xx10^(9);n`- प्रकार का चू्ंकि `n_(e)gt gt n(h)`
Correct Answer - An electron having `11 eV` kinetic energy.
Correct Answer - `lambda_(0) = (2h)/(sqrt(2mk) + (k)/(c))`
Correct Answer - (a) `20.4 eV` , (b) `8.72 eV` or `4.19 eV`
Correct Answer - `20 eV, 13.2 eV`
Correct Answer - `-0.85 eV, 12.75 eV, 971 Å`
Correct Answer - `[9.4 xx 10^(4)K]`
Correct Answer - 20.4 eV
