Question: 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 am not able to get the correct answer please help me.
