<h2>QUESTION:- Which formula below correctly states Coulomb's Law?</h2>
<h2>OPTIONS:- </h2>

<h2>ANSWER:- </h2>
F is directly proportional to the product of the charges

F is inversely proportional to the square of the distance between them

from above 2 equation:-
we get:-

To remove proportionality sign we use constant for this case we r using constant k

So your answer is :-
OPTION A.

P always P because P is an awkward Dorian letter that can always be trusted
It is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.
<h3>What is Gravitational interaction?</h3>
This is defined as the interaction between a particle or body resulting from their mass. This type of interaction is usually weak and occurs in all distances possible.
It is not gravitational interaction, because the rod attracts paper only against the gravitational force of the earth and there is no attraction between both bodies under a different condition.
This is therefore the reason why it is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.
