A potentiometer wire of 10m length and 20 ohm resistance is connented in series with a resistance “R” ohms and a battery of emf 2V , negligeble internal resistance , potential gradient on the wire is 0.16 millivolt/centimetre then “ R” _______ ohms?

Write first the total resistance = R
current in the circuit would be = V/R
remaining voltage/m = > 2/10 = 0.2 Volt/meter.
