[Urgent] Please help me out to solve this problem. You actually can skip writing down explanations, but equations, units and answer are required.

3. (25 points) Briefly answer the following 6 questions. Each question is 5 points with any one of them as extra credit. (a) What is the difference between electric field and Coloumb's force? (b) Explain what a Gaussian surface is. (c) What is the magnitude of the electric field between the conductors in a capacitor? (d) What is the magnitude of the electric field outside the conductors in a capacitor? (e) How is an ohmic material defined? (f) What the difference is between the electric potential and the electric potential energy? (g) Draw charges inside the R region so that the net electric field outside of the region is zero. R (h) Draw charges inside the R region so that the net electric field outside of the region is not zero. R (i) Explain with a few sentences what the voltage rule is (aka loop rule). (j) Explain with a few sentences what the current rule is (aka node rule). (k) Explain with a few sentences what the superposition principle is
