Concept: since the thickness of the gold foil is negligible, it has no effect on the capacitance and the capacitance remains same as before
***********************************************************************************************
This concludes the answers. If there is any mistake or
omission, let me know immediately and I will fix
it....

A parallel-plate capacitor has a plate area of A = 250 cm2 and a separation of d = 2.00 mm. The capacitor is charged to a potential difference of V0 = 150 V by a battery. A dielectric sheet (κ = 3.50) of the same area but thickness ℓ = 1.00 mm is placed between the plates without disconnecting the battery. (See figure 24-18 on page 642). Determine the initial capacitance of the air-filled capacitor. Determine the charge on the...

Chapter 25, Problem 037 Your answer is partially correct. Try again. The parallel plates in a capacitor, with a plate area of 7.60 cm2 and an air-filled separation of 4.50 mm, are charged by a 5.40 V battery. They are then disconnected from the battery and pulled apart (without discharge) to a separation of 6.40 mm. Neglecting fringing, find (a) the potential difference between the plates, (b) the initial stored energy, (c) the final stored energy, and (d) the work...
