Using finite difference method, determine potential and magnitude of electric field at free nodes in the potential system of figure, for the following conditions: 60 V a) h=1.5 cm, using conventional gauss-seidel method. / 12 cm b) h=1.5 cm, using improved gauss-seidel method. c) h=0.75 cm, using conventional gauss-seidel method. 0 d) h=0.75 cm, using improved gauss-seidel method. SOV Notes: In all conditions, assume that the initial guess for the potential of all free nodes is V;=1". X Convergence tolerance for all conditions is = 103 0 6 cm -30 V Number of iterations should be specify for each part
