State Heisenberg's uncertainty principle. If the uncertainties in the measurement of position and momentum of an electron are equal calculate the uncertainty in measuring the velocity.

Explanation

### Step-by-Step Solution:

1. **State Heisenberg's Uncertainty Principle**:
Heisenberg's uncertainty principle states that it is impossible to simultaneously know both the position (Δx) and momentum (Δp) of a particle with perfect accuracy. Mathematically, it is expressed as:
\[ Δx \cdot Δp \geq \frac{h}{4\pi} \]
where \( h \) is Planck's constant.
