Question

1. Consider a point charge +Q. What is bigger: its electric
field 2 m from this charge, or its potential 2 m from the
charge?

a. Electric field

b. Potential

c. They are equal.

d. These two can’t be compared.

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)
