A very long line charge having a charge density it is surrounded by a conducting cylindrical shell with inner radius ri = 5.16 cm and outer radius r0 = 7cm as shown in the gure. System is in electrostatic equilibrium condition. What would be the electric potential difference AV = V(r= 3.22 cm) V(r= 6.4 cm) ? Provide your answer in terms of itk with 2 signicant gures
