Question

For a point charge, how does the potential vary with distance from the point charge, r?

Answer 1

For a point charge, how does the potential vary with distance from the point charge, r?

a constant

b. r.

c. 1/r.

d. $1/r^2$.

e. $r^2$.

Answer:

The  correct option is  C

Explanation:

Generally for a point charge the electric potential is mathematically represented as

    $V = \frac{k Q }{r }$

Here we can deduce that the electric potential varies inversely with the distance i.e

      $V \ \alpha \ \frac{1}{r}$

So
