Question

Which of the following statements is true of hydrogen atom ?

• A. Angular momentum µ$\frac{1}{n}$
• B. Linear momentum µ$\frac{1}{n}$
• C. Radius µ$\frac{1}{n}$
• D. Energy µ$\frac{1}{n}$

Answer 1

Answer: (B)

Linear momentum µ$\frac{1}{n}$

Answer 2

We know that angular momentum

L = mvr = $\frac{nh}{2\pi}$ or mv = $\frac{nh}{2\pi r}$

Now, r µ n² \ mv = p µ$\frac{nh}{2\pi \times n^{2}}$

or p µ $\frac{h}{2\pi n}$or p µ $\frac{1}{n}$
