Q: Two equal and opposite charges, Q₁ = 2 C and Q₂ = -2C, are separated by a distance of 6m. What is the potential at the midpoint between these charges?
The potential at the midpoint between the two equal and opposite charges is 0 V. Since the charges have the same magnitude but opposite signs, their individual potentials cancel each other out, resulting in a net potential of 0 V.
