Three charges (q1=1 μC, q2=−2 μC, q3=3 μC) are located at the corners of an equilateral triangle with sides of length one meter. The 3 μC charge is:

Repelled by q1 and attracted by q2.

Attracted by q1 and repelled by q2.

Attracted by both q1 and q2.

Repelled by both q1 and q2.

Repelled by q1 and attracted by q2.

To determine the interaction between charges q1 and q3, we need to understand the concept of electric charge and how charges interact with each other.

Like charges repel each other, while opposite charges attract each other. In this scenario, q1 and q3 have opposite charges, with q1 being positive (+1 μC) and q3 being positive (+3 μC). Therefore, they attract each other due to the opposite charges.

On the other hand, q1 and q2 have the same charge, with q1 being positive (+1 μC) and q2 being negative (-2 μC). Since they have the same charge, they repel each other.

Given this information, we can conclude that the 3 μC charge (q3) is attracted by q1 and repelled by q2.

To determine the interaction between the 3 μC charge and q1 and q2, we need to consider the nature of electric charges. Like charges repel each other, while opposite charges attract each other.

In this case, the 3 μC charge is positive, and q1 and q2 have opposite charges: q1 is positive (1 μC) and q2 is negative (-2 μC). Therefore, the 3 μC charge will be attracted to q1 and repelled by q2.

Hence, the correct answer is: Attracted by q1 and repelled by q2.
