(a) Find the electric field between two plates which are separated along the y-axis Ay = 6.00 mm, where the bottom plate has a potential V₂ = 150. mV and the top plate has a potential V₁ = 5.00 mV. (b) What is the potential at a distance Ay' = 2.00 um from the bottom plate?arrow_forward4.8. The electric potential energy stored in any capacitor, dielectric filled or not, is given by: U = C(AV)´. When a dielectric material is inserted into the isolated, charged capacitor, does this stored energy increase or decrease? Use your factors from the previous questions 4.3 and 4.6 to determine by what factor this energy changes.arrow_forward
