Detailed Solution

Current through any cross-section should remain same as all the cross-sections are in series.I=neAvd, area increases drift velocity decreases. E is directly proportional to vd, so E also decreases. lf E decreases, then potential difference across a segment of fixed length also decreases.This can also be done like this:dR=ρdxA;  A  increases  with  x.Potential  across  dx:  dV =  IdR=IρdxAE=dVdx = IρA ∝  1ASo E and dVdx both decrease as A increases.
