A straight wire carries a current of 10A. An electron moving at `10^(3)` m/s is at distance 2.0 cm from the wire. Find the force acting on the electron if its velocity is directed toward the wire?

Explanation

To find the force acting on the electron due to the magnetic field created by the current-carrying wire, we can follow these steps:

### Step 1: Determine the magnetic field (B) around the wire
The magnetic field (B) around a long straight current-carrying wire is given by the formula:

\[ B = \frac{\mu_0 I}{2\pi r} \]
