Solving a problem in physics section 69 point 26 electr

26. A potential difference U1 = 1.5 kV is applied to the plates of a flat air condenser. The area of the plates is S = 150 cm2, the distance between them is d = 5 mm. With the voltage source turned on, glass was introduced between the plates (ε = 7). Determine the potential difference U2 between the plates after making the dielectric. Also determine the capacitance of capacitor C1 and C2 before and after making the dielectric.
