In a meter bridge, the wire of length 1 m has a non-uniform cross-section such that, the variation dR/dl of its resistance R with length l is dR/dl ∝ 1/√l. Two equal resistance are connected as shown in the figure. The galvanometer has zero deflection when the jockey is at point P. What is the length AP?
