**Problem Statement:**

In the figure, a conducting rod of length \( L = 40.0 \, \text{cm} \) moves in a magnetic field \( \mathbf{B} \) of magnitude \( 0.410 \, \text{T} \) directed into the plane of the figure. The rod moves with speed \( v = 5.60 \, \text{m/s} \) in the direction shown.

**Diagram Explanation:**

The diagram illustrates a conducting rod, labeled from point \( a \) to point \( b \), moving in a uniform magnetic field \( \mathbf{B} \) directed into the plane (denoted by crosses). The rod is perpendicular to the direction of motion, with length \( L \) indicated and velocity \( v \) shown by an arrow pointing diagonally downwards to the right.

**Part E:**

When the charges in the rod are in equilibrium, which point, \( a \) or \( b \), has an excess of positive charge?

- \( \text{o} \) \( a \)
- \( \text{o} \) \( b \)

**Part F:**

What is the potential difference across the rod if it moves parallel to \( ab \)?

Express your answer in volts.

\[ V = \text{\_\_\_\_\_} \, \text{V} \]
