Increasing the distance by a factor of two from a point charge will change the electric potential by a factor of __ A 1/2 B. 2 C. 4 D 1/4

Question

Answer 1

The electric potential (V) due to a point charge (q) is given by the equation:

where:-

is Coulomb's constant,-

is the charge,-

is the distance from the charge.If the distance

is increased by a factor of two, the new distance becomes

. Substituting

into the equation for electric potential, we get:

Now, we compare the new potential

with the original potential

:

Thus, the electric potential changes by a factor of

.So, the correct answer is:A.
