A uniform electric field has magnitude E and is directed in the negative x-direction. The potential difference between point a (at x = 0.60 m) and %3D point b (at x = 0.90 m) is 240 V. A negative point charge q = -0.200 mC moves from a to b. Calculate the work done on the point charge by the electric field.

Two plates of area 30.0 cm? are separated by a distance of 0.0480 cm. If a charge separation of 0.0640 µC is placed on the two plates, calculate the potential difference (voltage) between the two plates. Assume that the separation distance is small in comparison to the diameter of the plates. potential difference: V

Consider a parallel-plate capacitor whose (circular) plates are separated by a 3.0-mm-thick slab of glass with dielectric constant 5.0. The diameter of each plate is 4.0 cm, and the slab fills the entire volume between the plates. The electric field between the plates with the dielectric in place has magnitude 8.0 x 103 V/m. (a) Find the magnitude of the charge on either plate of the capacitor. (b) Now suppose the slab of glass is removed, leaving an air gap between the plates. Calculate the total energy stored in this capacitor and the energy density (energy per unit volume).
