You have a conducting ball of radius a, on which electric charge Q is uniformly distributed. (1) With an assumption that V(x) = 0 as a reference, find the distribution of electric field E and potential V. (2) Now, you have two conducting balls 1 and 2 of radius a and az, respectively. They are aligned along the z-axis, as illustrated below, and separated from each other by D >> ai, If we define coefficients of potential as 42 Ball 2: radius:a Ball 1: radius: a [] = P P [&:] find the coefficients of potential p (ij = 1,2). Here, Vi and Qi represent the potential of and the charge distributed on the i-th conducting ball (i = 1,2).
