Expert Answer

 Question:In a certain region of volume 0.2m3 of space, the electric potential is found everywhere to be 5V. The magnitude of the electric field in this region is

Given that,

Volume, dv = 0.2 m3

Electric potential, V’ = 5 V (Constant)

Magnitude of electric field, E = ?

Now,

Relation between electric field and potential is given as

 E equals negative fraction numerator d V over denominator d r end fraction i. e. comma space E equals negative fraction numerator d left parenthesis 5 right parenthesis over denominator d r end fraction equals 0 space

 Hence option D is correct.
