Two very large concentric spherical shells of radii a=143m and b=359 m carry uniform charges Q and -Q as shown in the figure below. If the electric field between the shells isE =r2where Q=8µC, 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 youranswer is negative. Take the value of Coulomb constant as k=9x109 N.m2/c2. Hint: here the unit vector r is radially outward.---

Given that the electric field between the two concentric spheres is:
