AI Generated Solution
To find the order of the velocity of an electron in a hydrogen atom in the ground state, we can follow these steps:
### Step 1: Understand the formula for electron velocity in a hydrogen atom
The velocity of an electron in the nth orbit of a hydrogen atom is given by the formula:
\[
v_n = \frac{e^2}{2 \epsilon_0 n h}
\]
where:
