Suppose electric potential varies along the x-axis as shown in the above figure the potential doesnot vary in `y or z` direction of the intervals shown (ignore the behaviour at the end points of the intervals) the field `E_(x)` has a maximum absolute value `\"FB_(1)\"Vm^(-1)` in the region `\"FB_(2)\"` its value in the region cd is `\"FB_(3)\"Vm^(-1)` then The value that fills `\"FB_(1)\"` is
