Final answer:
The electric potential at the midway point between two opposite charges is zero.
Step-by-step explanation:
The subject of this question is Physics, specifically the topic of electric charges and electric potential. The question involves two opposite charges separated by a distance and asks about the electric potential at the midway point.
To solve this problem, we can use the formula for electric potential:
Electric potential (V) = k * Q / r
where k is the electrostatic constant (9 x 10^9 Nm²/C²), Q is the charge, and r is the distance.
Since the charges are opposite in sign and have the same magnitude, their potential cancels out at the midway point (where the distance is half of the total separation). Therefore, the electric potential at the midway point is zero.
