A parallel-plate capacitor has plates of area 364times104

Question

Compute each part of given question:

Question: A parallel-plate capacitor has plates of area 3.64×10⁴ m².

Part A: What plate separation is required if the capacitance is to be1610 pF? Assume that the space between the plates is filled with air? (Dielectric constant for air is 1.00059) wants the answer in um.

Part B: What plate separation is required if the capacitance is to be 1610 pF? Assume that the space between the plates is filled with paper. (Dielectric constant for paper is3.7) wants the answer in um.

Please show all work and steps for above question how to solve!
