The Eq. (7) becomes 2 2 I GA K k   (12) Similarly | |  u C Dr r   (13) At point I of Fig. 7 u=0 Hence, in the limiting condition 0 | | lim r u C r   (14) and Eq. (8) becomes, 2 1 II GC K k    (15) Similarly for evaluating K III , using | | w E Fr r   (16) and at point I of Fig. 7 w=0 and Eq. 9 in the limiting condition becomes, 0 | | lim  r w E r   (17) Thus, Eq. 9 becomes 2 III K GE   (18)
