When charge Q₁ is placed at point P₁,the resulting potential at point P is V₁.When Q₂ is placed at point P₂ after Q₁ is in position at P₁,the resulting potential at P becomes V₂.What is the potential at point P if charge Q₁ is then removed? A)V₁ + V₂ B)V₁ - V₂ C)V₂ - V₁ D)(V₁ + V₂)/2

Question

Quizplus · Accepted Answer

The potential at a point due to multiple charges is the algebraic sum of the potentials due to each charge individually. When Q₁ is removed, the potential at point P is solely due to Q₂, which is already included in the total potential V₂. Therefore, the potential due to Q₁ must be subtracted from V₂ to find the new potential at P.
