Two 2.20cm × 2.20cm plates that form a parallel-plate capacitor are charged to± 0.708 nC.
What is the electric field strength inside the capacitor if the spacing among the plates is 1.40mm?
What is potential difference across the capacitor if the spacing among the plates is 1.40mm?
What is the electric field strength inside the capacitor if the spacing between the plates is 2.80mm?
What is the potential dissimilarity across the capacitor if the spacing between the plates is 2.80mm?
