Limitations of Bohr Atomic

Model Theory:

It failed to explain the Zeeman effect when the spectral line is split into several components in the presence of a magnetic field. It failed to explain the Stark effect when the spectral line gets split up into fine lines in the presence of an electric field.

evaluate using the given identity.

${a}^{2} - {b}^{2}$

solve the following

(1)$207 \times 303$

(2)$78 \times 82$

(3)$102 \times 98$

$\huge\fbox\green{Solution:-}$

$(1) \: 207 ×303 \\ we \: know \: that: \\ {a}^{2} - {b}^{2} = (a + b)(a - b) \\ → (300 + 3)(300 - 3)\\ → {300}^{2} - {3}^{2} \\ → 90000 - 9 \\ = 9991$

$(2)\:78×82 \\we \: know \: that: \\ {a}^{2} - {b}^{2} = (a + b)(a - b)\\ →(80+2)(80-2)\\{80}^{2} - {2}^{2}\\ → 6400 - 4 \\ = 6399$

$(3) \: 102 \times 98 \\ we \: know \: that: \\ {a}^{2} - {b}^{2} = (a + b)(a - b) \\ →(100 + 2)(100 - 2) \\ → {100}^{2} - {2}^{2} \\ →10000 - 4 \\ =9996$

Let d1 be the diameter of the moon and d2 and be the diameter of the earth.Let r1 be the radius of the moon and r2 be the radius of the earth.

$given \: d1 = \frac{1}{4}d2 \\ = > 2r1 = \frac{1}{4} ×2r2 \\ =>r1 = \frac{1}{4}×r2 \\ Now, \: ratio \: of \: \: their \: surface \: areas \: is: \\ = s1: s2 \\ = r {1}^{2}: r {2}^{2} \\ = {1}^{2 } : {4}^{2 } \\ =1:16$
