The uncertainty in position of an electron in equal to its de Broglie wavelength .The minimum percentage error in de measuremebnt of velocity under this circumstance will be approsimately

Options

A. 4
B. 8
C. 22
D. 18

Explanation

To solve the problem, we need to find the minimum percentage error in the measurement of velocity of an electron when the uncertainty in its position is equal to its de Broglie wavelength. We will use the Heisenberg Uncertainty Principle and the relationship between momentum and velocity.

### Step-by-Step Solution:

1. **Understanding the Heisenberg Uncertainty Principle**:
The Heisenberg Uncertainty Principle states that:
\[
\Delta x \cdot \Delta p \geq \frac{h}{4\pi}
