Question

In the graph between $\sqrt{v} \& z$ for mosley's equation, $\sqrt{v}=a(z-b),$ the intercept $O X$ is 1 on $\sqrt{v}$ axis.

What is the frequency $v$ when atomic $No . Z=52 ?$

• A. $7.14 s ^{-1}$
• B. $7 s ^{-1}$
• C. $2401 s ^{-1}$
• D. $2601 s ^{-1}$

Answer 1

Answer: (D)

slope $=a=\tan 45^{\circ}$

$a=1$

$a b=1(O X)$

$1 \times b=1 \Rightarrow b=1$

$\sqrt{v}=1 \times 52-1 \times 1$

$\sqrt{v}=52-1$

$\sqrt{v}=51$

$(\sqrt{v})^{2}=(51)^{2}$

$v=2601$
