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
