The electrical potential between two point charges of 3.4 microC and 6.6 microC, separated by 0.10 m, can be calculated using the formula V = kQ/r, where k = 8.99 x 10^9 Nm^2/C^2. The potential at the midpoint is the sum of the potentials due to each charge, calculated at a distance of 0.05 m from each charge. It is crucial to note that the potential does not include a negative sign, as the potential increases as one approaches a positive charge.

Doc Al said:The potential at a distance "r" from a point charge of Q is given by:
V = \frac{kQ}{r}
The minus sign is incorrect. The potential increases as you get closer to a positive charge. (The zero potential is taken to be at r = ∞.)jatin9_99 said:V= -kQ/r i just added a negative sign to it to make it more sophesticated
