Question

please help me Q4 and Q5 

Two parallel plates, each having area A = 2080cm2 are connected to the terminals of a battery of voltage Vp = 6 V as shown. The plates are separated by a distance d = 0.44cm. You may assume (contrary to the drawing) that the separation between the plates is small compared to a linear dimension of the plate. d 1) What is C, the capacitance of this parallel plate capacitor? 0.000419 uF Submit 2) What is Q, the charge stored on the top plate of the this capacitor?. 0.0025 uC Submit 3) A dielectric having dielectric constant K = 4,1 is now inserted in between the plates of the capacitor as shown. The dielectric has area A = 2080 cm2 and thickness equal to half of the separation (= 0.22 cm) . What is the charge on the top plate of this сарacitor? A 0.004038 uC Submit 4) What is U, the energy stored in this capacitor? J Submit 5) The battery is now disconnected from the capacitor and then the dielectric is withdrawn. What is V, the voltage across the capacitor? A V=? d V Submit
