Two large parallel metal plates are 1.5 cm apart and have charges of equal magnitudes but opposite signs on their facing surfaces. Take the potential of the negative plate to be zero. If the potential halfway between the plates is then `+10.0 V`, what is the electric field in the region between the plates?

Explanation

To find the electric field between two parallel plates with given potentials, we can follow these steps:

### Step 1: Understand the Problem
We have two large parallel plates that are 1.5 cm apart. The negative plate has a potential of 0 V, and the potential halfway between the plates is +10.0 V. We need to find the electric field (E) in the region between the plates.

### Step 2: Identify the Relevant Formula
The electric field (E) between two parallel plates can be calculated using the formula:
\[ E = \frac{V}{d} \]
