The correct Answer is:
To find the electric field between two plates when a potential difference is applied, we can use the formula: \[ E = \frac{V}{d} \] where: - \( E \) is the electric field (in volts per meter or V/m), - \( V \) is the potential difference (in volts), - \( d \) is the distance between the plates (in meters). ### Step-by-Step Solution: 1. **Identify the given values:** - Potential difference \( V = 10 \) volts - Distance between the plates \( d = 2 \) cm 2. **Convert the distance from centimeters to meters:** \[ d = 2 \text{ cm} = 2 \times 10^{-2} \text{ m} = 0.02 \text{ m} \] 3. **Substitute the values into the formula for electric field:** \[ E = \frac{V}{d} = \frac{10 \text{ volts}}{0.02 \text{ m}} \] 4. **Calculate the electric field:** \[ E = \frac{10}{0.02} = 500 \text{ V/m} \] 5. **Convert the unit of electric field to Newton per coulomb (N/C):** Since \( 1 \text{ V/m} = 1 \text{ N/C} \), we have: \[ E = 500 \text{ N/C} \] ### Final Answer: The electric field between the plates is \( 500 \text{ N/C} \). ---
