Expert Answer:

The relation between the electric field (E) and electric potential (V) is
 
begin mathsize 12px style straight E equals negative dV over dr end style
 
i.e. electric field is rate of change of potential with distance.
 
Now, it is given that the potential is constant (5 V) throughout the volume of 0.1 m3.
 
Hence, we can say that in the region of space given, the potential is constant w.r.t distance r.
 
Hence, we get
 
begin mathsize 12px style dV over dr equals 0 therefore straight E equals 0 end style
