the potential decreases uniformly from V1 to V2
along x - axis in a coordinate system as one moves
from ( - a,0) to (+a,0). The field at origin is
(a) must be (V1 - V2)/2a
(b) cannot be less than (V1-V2)/2a
(c)must be smaller than (V1-V2)/2a
(d) must be greater than (V1-V2)/2a
ans is (b)
plzzzz .... explain whyy????

33see Ex will be (V1-V2)/2a
but what about Ey and Ez so it can,t be less than (V1-V2)/2a
So E≥(V1-V2)/2a
(equality holds when Ey=Ez=0)
