An electric dipole is formed by two charges +q and -q located in xy-plane at (0, 2) mm and (0, -2) mm, respectively, as shown in the figure. The electric potential at point P(100, 100) mm due to the dipole is V₀. The charges +q and -q are then moved to the points (-1, 2) mm and (1, -2) mm, respectively. What is the value of electric potential at P due to the new dipole ?

Step 1: Use V = Σ[kqᵢ/rᵢ] for discrete charges or integrate dV = k dq/r for a continuous distribution. If a field is given, use ΔV = -∫𝐄·d𝐥. Step 2: Potential is a scalar, so contributions add algebraically. Step 3: Insert the stated distances/charge distribution and simplify. Final: B: V₀ /2.
