Two point charges, +Q and -Q, are placed at a distance d apart. What is the electric potential at the midpoint between the charges?

Two point charges, +Q and -Q, are placed at a distance d apart. What is the electric potential at the midpoint between the charges?

Correct Answer: 0

Step 1: Identify the two point charges. We have a positive charge (+Q) and a negative charge (-Q).
Step 2: Determine the distance between the two charges. They are placed at a distance 'd' apart.
Step 3: Find the midpoint between the two charges. This point is located exactly halfway between +Q and -Q.
Step 4: Understand that electric potential (V) is a scalar quantity. This means we can add the potentials from each charge algebraically.
Step 5: Calculate the electric potential due to +Q at the midpoint. The potential is positive.
Step 6: Calculate the electric potential due to -Q at the midpoint. The potential is negative.
Step 7: Add the potentials from +Q and -Q at the midpoint. Since one is positive and the other is negative, they will cancel each other out.
Step 8: Conclude that the total electric potential at the midpoint is zero.
