Two very long L=58m concentric cylindrical shells of radii a=11cm and b=43 cm carry uniform charges Q and -Q as shown in the figure below. Tf the electric field between the shells is = 2k Lr where Q=1.1pC, determine the potential difference between the shells; V(b)-V(a)=? Express your answer in units of Volts using zero decimal places. Please do not forget a minus sign if your answer is negative. Take the value of Coulomb constant as k=9x10° N.m2/c2. Hint: here the unit vector r is radially outward.
