Final answer:
A particle with charge 13 nC is located at the origin.
The correct option is a.
Step-by-step explanation:
The question is asking whether the statement "A particle with charge 13 nC is located at the origin" is true or false. To determine this,
we need to first understand what charge is. Charge is a fundamental property of matter, and it can be positive or negative. Positive charges repel each other,
while negative charges attract each other. So, if a particle has a positive charge of 13 nC, it will repel other positively charged particles and attract negatively charged particles.
Therefore, the correct answer is a) True.
