The resistance with respect to the radius changes

Reference no: EM131105830

The electric resistance of a wire is inversely proportional to the square of its radius. If a certain wire has a resistance of 0.30 Ω when its radius is 2.0 mm, find the average value of the resistance with respect to the radius changes from 2.0 mm to 2.1 mm.
