Math Problem Statement

Two plates with area 5.00 × 10^−3 m^2 are separated by a distance of 4.80 × 10^−4 m. A charge of 4.40 × 10^−8 C is moved from one plate to the other. Calculate the potential difference (ΔV) between the two plates.

Solution

The problem in the image asks to calculate the potential difference (ΔV) between two plates, given the following parameters:

  • Area of the plates: A=5.00×103m2A = 5.00 \times 10^{-3} \, \text{m}^2
  • Separation distance: d=4.80×104md = 4.80 \times 10^{-4} \, \text{m}
  • Charge moved from one plate to the other: Q=4.40×108CQ = 4.40 \times 10^{-8} \, \text{C}

The plates form a parallel plate capacitor, and the potential difference between the plates is given by:

ΔV=Qdϵ0A\Delta V = \frac{Qd}{\epsilon_0 A}

where:

  • ϵ0\epsilon_0 is the permittivity of free space: ϵ0=8.85×1012F/m\epsilon_0 = 8.85 \times 10^{-12} \, \text{F/m}.

Now, let's calculate the potential difference using the given values.The potential difference (ΔV) between the two plates is approximately 477.29V477.29 \, \text{V}.
