Using Searle's apparatus while determining the Young's modulus of a wire, a girl is taking measurements of different parameters : Length of the wire, L, is 30 cm, which is measured with a millimeter scale , diameter of the wire, d, is 1 mm, which is measured with a screw gauge. (Least count of the screw gause is 0.01 mm, least count of the spherometer attached to the apparatus frame is 0.005 mm, spherometer attached to the apparatus frame is 0.005 mm , spherometer measured the extension e of the wire , W is the weight of the loads.) The parameter that should be measured more carefully is
