A fuel gauge uses a capacitor to determine the height of the fuel in a tank. The effective dielectric constant κchanges from a value of 1 when the tank is empty, to a value of 7, when the tank is full. The appropriate electronic circuitry can determine the effective dielectric constant of the combined air and fuel between the capacitor plates. The dimension of the fuel tank is width w=19cm, length L=12cm and breadth d=18cm. The height of the fuel between the plates is h=7cm. A battery with e.m.f of 13v is connected across the plates.

In the diagram, an isolated charged parallel-plate capacitor holding charge Q isarranged horizontally, with one plate flush with a frictionless surface. The capacitor hascapacitance Co when there is no dielectric inserted. The dielectric block (mass m, dielectricconstant k) inside the capacitor is attached to a hanging block (mass M) by a massless stringrouted over a frictionless pulley.

The blocks are initially at rest and the dielectric is initially completely inside thecapacitor. Use conservation of mechanical energy to determine the speed v of thefalling block at the moment the dielectric block completely exits the capacitor plates(in other words, determine a formula for the speed in terms of the variousparameters that have been defined as algebraic variables).b.
