Two point charges, +3.45 µC and -6.50 µC, are separated by 1.19 m. What is the electric potential midway between them?

To find the electric potential midway between two point charges, we need to calculate the electric potential created by each charge and then sum them up.

The electric potential created by a point charge can be calculated using the formula: V = k * Q / r, where V is the electric potential, k is the electrostatic constant (9 x 10^9 Nm^2/C^2), Q is the charge, and r is the distance from the charge.

Let's start by calculating the electric potentials created by each charge:

For the positive charge (+3.45 µC), the electric potential V1 = (9 x 10^9 Nm^2/C^2) * (3.45 x 10^-6 C) / (0.595 m)

For the negative charge (-6.50 µC), the electric potential V2 = (9 x 10^9 Nm^2/C^2) * (-6.50 x 10^-6 C) / (0.595 m)

Now, let's calculate the electric potential midway between the charges:

The electric potential at the midpoint will be the average of V1 and V2, as the potential is a scalar quantity.

V_midpoint = (V1 + V2) / 2

Substituting the values, we have:

V_midpoint = ((9 x 10^9 Nm^2/C^2) * (3.45 x 10^-6 C) / (0.595 m) + (9 x 10^9 Nm^2/C^2) * (-6.50 x 10^-6 C) / (0.595 m)) / 2

By evaluating this expression, you can find the electric potential midway between the two charges.
