The mean free path of conduction electron in a metallic block is `5xx10^(-6)` m the block is placed in an electric field of `5xx10^(+7) v m^(-1)` calculate the energy of the conduction electron in the block

Explanation

To calculate the energy of the conduction electron in the metallic block placed in an electric field, we can follow these steps:

### Step 1: Understand the relationship between energy, force, and displacement.
The energy (E) gained by a charge in an electric field can be expressed as:
\[ E = F \cdot d \]
where \( F \) is the force acting on the charge and \( d \) is the displacement (mean free path in this case).

### Step 2: Calculate the force on the conduction electron.
