A potentiometer wire is 10 m long and a potential difference of 2.5 volt is attached between its two ends.the null point is obtained at a distance of 6m from common end.when a shunt resistance of 1 ohm is connected across the cell,the null point shifts to 3m.Find the potential gradient,e.m.f. of the cell and internal resistance of the cell.
