If a current passes through a metal conducting wire of area of cross section A, the drift velocity of free electrons inside the metal is v_d=1/( n e A) , where the amount of electric charge of an electron =e and the number of free electrons per unit volume of the metal=n. The applied electric field on the wire is E=V/l , where a potential difference V exists between two points, l apart, along the length of the wire. IF R is the resistance of the wire between those two points, then the resistivity of its material is rho=(RA)/l .Besides the mobility (mu) of the free electrons inside a wire is defined as their drift velocity for a unit applied electric field. The radii of two wires of the same metal are in the ratio 1:2 The same potential difference is applied between two points at a distance l on each of the wires.The ratio between the drift velocities of the free electrons in two wires is

Electrons starting from rest and passing through a potential difference of 60 kV are found to acquire a velocity of 1.46 xx 10^(10) cm cdot s^(-1) . Calculate the ratio of charge to the mass of an electron.

Two wires are of lengths 1 cm and 2 cm and their diameters are 1 mm and 2 mm respectively. The wires are joined in series and on this combination a potential difference of 4.5 V is applid.If both the wires are made of the same material , determine the terminal potential difference across the shorter wire.
