2- Two long, coaxial, cylindrical conducting surfaces (each of length L, and of inner radius a and outer radius b) are used for constructing a capacitor by lowering them vertically into a liquid dielectric of mass density p. [Figure 4.32 on pp.205 of Griffiths (4th ed.) can help you visualize the setup. a) Determine the capacitance of this configuration if the liquid has risen a distance h < L between the electrodes when a potential difference V is established between them b) Determine the electric susceptibility Xe of the liquid. Hint: Carefully consider 'the balance of energy' by keeping an eye on the work done against gravity
