I assume this question is getting null point in meter bridge.
we know in meter bridge, at null point, ..........................(1)
where R and S are resistances and l1 is the reading of meter scale corresponding to the location of wire at null point.
Since in given question resistance is known, hence we know the ratio of R/S. From the known ratio we can solve the RHS of eqn.(1) to get l1 .
Hence null point is obtained for given R/S value at l1 cm in the meter scale.
