Question
The first figure shows a rectangular solid conductor of edgelengths L, 2L, and 3L. A potentialdifference V is to be applied uniformly between pairs ofopposite faces of the conductor as in part b of the secondfigure. First V is applied between the left-right faces(LR), then between the top-bottom faces (TB), and then between thefront-back (FB) faces. Rank those pairs, greatest first, accordingto the following properties. (Use only the symbols > or =,for exampleLR>TB=FB.)

Rank those pairs, greatest first, accordingto the following properties. (Use only the symbols > or =,for exampleLR>TB=FB.)Explanation / Answer
a) TB>FB>LR
b) TB>FB>LR.
c)TB>FB>LR.
d)TB>FB>LR.
since E=keA/d, e and A are constants so simply plug in and compare the TB to the FB to the LR
