In a meter bridge, the wire of length 1 m has a non-uniform cross-section such that, the variation \frac{dR}{dl} of its resistance R with length l is \frac{dR}{dl} α 1/\sqrtl. Two equal resistances are connected as shown in the figure. The galvanometer haszero deflection when the jockey is at point P. What is the length AP? [12 Jan 2019 Shift 1]
