The force F between two charges Q1 and Q2 in a vacuum is proportional to the product of the charges and is inversely proportiona
1 answer:
Answer:
<h3>The given statement "The force F between two chargesStep-by-step explanation:
Given that "The force F between two charges and
in a vacuum is proportional to the product of the charges and is inversely proportional to the square of the distance between two charges"
Coulomb's law states that the magnitude of the electrostatic force F of attraction or repulsion between the two point charges and
is directly proportional to the product of the magnitudes of charges
and
and it is inversely proportional to the square of the distance between the two charges.

Given:
Four equations in the options.
To find:
The equation which represents a proportional relationship.
Solution:
If y is proportional to x, then
where, k is the constant of proportionality.
In this case if x=0, then y=0. It means the graph of a proportional relationship passes through the origin.
From the given options, only option B, i.e., , is of the
, where,
.
So, the equation represents a proportional relationship.
Therefore, the correct option is B.
