Question

Problem: When a potential difference of 188 V is ap- plied to the plates of a parallel-plate capacitor, the plates carry a surface charge density of magnitude 43 nC/cm².

Part A: What is the spacing between the plates? The value of the permittivity of a vacuum is 8.8542 × 10¹² C²/N•m².

I need the right answer and steps of solve above problem.
