Question
Two very large concentric spherical shells of radii a=153m and b=389 m carry uniform charges Q and -Q as shown in the figure below. If the electric field between
the shells is
E = k-
r2
where Q=7µC, determine the potential difference between the shells; V(a)-V(b)=? 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.
