In fig.25-46 two parallel plate capacitors (with air between the plates) are connected to a battery. Capacitor 1 has a plate area of `1.5 cm^2` and an electric field of magnitude `3500 V//m`. Capacitor 2 has a plate area of `0.70 cm^2` and an electric field of magnitude `1500 V//m` (a) What is the total charge on the two capacitors? (b) If the first plate area is cut in half does the total charge increase, decrease, on remain the same?

Explanation

`a) 5.6 times 10^-12 C` (b) decreasing area decrease the charge q
