question 68

Multiple Choice

A charge q₁ is placed on the y-axis at y = 4.0 m and the resulting potential at the position (3.0 m, 4.0 m) is 3.0 V. The charge q₁ is removed and a charge q₂ is placed on the x-axis at x = 3.0 m and the resulting potential at the position (3.0 m, 4.0 m) is 4.0 V. If both charges are in place simultaneously, what is the potential at (3.0 m, 4.0 m) ?

• A) 1.0 V
• B) 3.5 V
• C) 5.0 V
• D) 7.0 V
• E) 12 V
