question 133

Multiple Choice

Two point charges of +2.00 μC and +4.00 μC are at the origin and at the point x = 0.000 m, y = -0.300 m, as shown in the figure. What is the electric potential due to these charges, relative to infinity, at the point P at x = 0.400 m on the x-axis? (k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C²)

• A) 117 kV
• B) 15.7 kV
• C) 11.7 kV
• D) 56.0 kV
