With what velocity should as `alpha`- particle travel toward the nucless of a copper atom at a distance of `10^(13)m` from the nucless of the copper atom ?

Explanation

To solve the problem of determining the velocity with which an alpha particle should travel toward the nucleus of a copper atom at a distance of \(10^{-13}\) m, we can follow these steps:

### Step 1: Understand the Forces Involved
The alpha particle is positively charged and will experience a repulsive force due to the positively charged nucleus of the copper atom. The potential energy associated with this electrostatic interaction can be calculated using Coulomb's law.

### Step 2: Calculate the Potential Energy
The potential energy \(U\) of the alpha particle at a distance \(r\) from the nucleus can be calculated using the formula:
\[
