43:50 ans is 9:5 But we neednt put the value of R as it is a constant and gets cancelled out while taking ratio

Don't put R value it will cut down in ratio

Pro tip for doing the ratio questions - don’t use the value of R ,it can be canceled out easily on dividing which makes the question easier . Hope this helps :)

Sir if we don't put the value of R in 43:46 then the ratio is coming 9:5 can we write that pls reply 🥺

Ya I was also thinking the same why sir has put the value of R there as it will obviously be cut down while taking ratio ...my ans is also coming same 9:5

behen dono se same aa rhi hai I thik u have not applied formula correctly it is 2 x pie x r= n lemda ..... in which r ka formula hai n^2 x r( not) yaha r(not)=0.53 angstrom so it will become 2 x 3.14 x 4(2 ka square kiya kyuki n=2 first excited state) x 0.53 = 2 lemda .....so ans 6.63 angstrom 👍👍👍👍
