Answer #1

the Electric field due to a point charge at distance r is given by

and the potential due to a point charge at distance r is

given by

... And In terms of E, it may be written as V= Er.

these two Electric field (E) and potential difference (V) are two different quanties.. So these can't be compared.

Option (d)

We only compare the two similar quanties that which one larger or smaller.. ( in terms of magnitude it can be calculated by using the above formulae)
