question 89

Multiple Choice

Two very small $+ 3.00 - \mu \mathrm { C }$ charges are at the ends of a meter stick. Find the electric potential (relative to infinity) at the center of the meter stick. $\left( k = 1 / 4 \pi \varepsilon _ { 0 } = 8.99 \times 10 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } \right)$

• A) \(1.08 \times 10 ^ { 5 } \mathrm {~V}\)
• B) \(2.70 \times 10 ^ { 4 } \mathrm {~V}\)
• C) \(0.00 \mathrm {~V}\)
• D) \(5.40 \times 10 ^ { 4 } \mathrm {~V}\)
