Write the principle of working of a potentiometer. Describe briefly, with the help of a circuit diagram, how a potentiometer is used to determine the internal resistance of a given cell.

Explain Poiseuille's formula for the volume of liquid flowing through a capillary tube - Describe an experiment to determine the coefficient of viscosity of a liquid by Poiseuiles formula.

In the arrangement as shown, A and B arc two cylinders each of length L and density d_1 and d_(2)(d_(1)ltd_(2)) respectively. They are joined together and submerged in the liquid of density d with length L//2 of A outside the liquid. If the difference in densities of two cylinders is equal to density of the liquid, find d_(1) .
