A parallel plate capacitor has a charge on one plate of q = 1.3E-06 C. Each square plate is d1 = 2.2 cm wide and the plates of the capacitor are separated by d2 = 0.65 mm. The gap is filled with air, ?o = 8.85 × 10-12 C2/Nm2.
Part (a) What is the voltage between the plates, ?V, in V?
Part (b) What plate width would double this voltage in cm?
