In the context of calculating total potential, the correct choice involves summing the variables that are representative of different potentials within a system. Specifically, when dealing with potentials, the symbols V₊ and V₋ typically represent positive and negative potentials, or electric potentials at various points in an electric field.

Electric potential (often denoted as V) is a scalar quantity that represents the potential energy per unit charge at a point in an electric field. By summing V₊ and V₋, you can find the total electric potential due to multiple sources of charge, taking into account how their individual potentials contribute to the overall potential experienced at a specific point in space. This summation is vital for understanding how potentials combine, especially when charges interact within an electric field.

Other options refer to different physical quantities that do not directly relate to the calculation of total potential in the same manner. For example, p and E relate to pressure and electric field strength, respectively, while q represents charge and V represents potential, but they do not indicate the sum of potentials. Similarly, τ and θ are associated with torque and angle, which are not relevant to the context of electric potentials.

Thus, the choice involving V₊ and V₋ correctly
