1. The problem statement, all variables and given/known data A capacitor with two parallel plates of area 88.5 cm2 and nylon (dielectric strength 14 MV/m) inserted between them breaks down when a potential difference of 5.80 kV is applied. What is the maximum charge the plates will hold when the nylon is removed and the space filled with air (dielectric strength 3 MV/m)? 2. Relevant equations Q = CΔV ΔV = Ed Co = εoA/d Coκ = εoAκ/d E = Eo/κ 3. The attempt at a solution The maximum electric field with the nylon inserted is 14 MV/m. ΔV = Ed and we have 5800 V applied. Solving for d gives d = 0.00041429 m. The maximum electric field once the nylon removed is 3 MV/m. ΔV = Ed. Solving for ΔV gives ΔV = 1242.87 V. C = εoA/d gives C= 1.89*10^-8 F. Q = CΔV = (1.89*10^-8 F)(1242.87 V) = 0.0000235 C. The online assignment page is rejecting my answer. Where am I going wrong?
