Dear Roshini Mam.... Thank you so much for this wonserful lecture...Lots of love and salute to your hard work and dedication.. We are eagerly waiting for this.. Next wait_ Ray Optics ....
1:20 u told that radius of atom will be 5 km from nucleus but mam it is generally used that radius or nuclei is 10-¹⁵m and radius of atom is 10-¹⁰m so it atom have 10⁵m radius large than of nuclei how it can be in km it will be in 100km
In topic Bohr's Radius formula of v² was : v²=Ze²/4×pi×Eo×m×r By this formula answer is coming correct but you have skipped r in this formula , still you wrote correct answer at the end.
