Electric Potential of Multiple Point Charges
Three point charges are located on the x-axis: q₁ = +2.0 μC is at x = 0 m, q₂ = -3.0 μC is at x = 2.0 m, and q₃ = +1.0 μC is at x = 5.0 m. At which position on the x-axis is the net electric potential zero?
A
x = 20 m
B
x = 3.5 m
C
x = -1.5 m
D
x = 7.0 m
