Calculate the resistance of 100 m length of a wire having a uniform cross-sectional area of 0.1 mm² if the wire is made of manganin having a resistivity of 50 x 10-8 Q-m. If the wire is drawn out to three times its original length, by how many times would you expect its resistance to be increased? [500 0; 9 times]
