Five identical conducting plates
1, 2, 3, 4 and
5 are fixed parallel to and equidistant from each other (see figure). Plates
2 &
5 are connected by a conductor while
1 &
3 are joined by another conductor. The junction of
1 &
3 and the plate
4 are connected to a source of constant e.m.f.
V0. Find:
(i) The effective capacity of the system between the terminals of the source.
(ii) the charges on plates
3 &
5Given
d= distance between any successive plates &
A= area of either face of each plate
