Two Long Parallel Wires That Are $0.30 \mathrm {~m}$ Apart Carry Currents Of

question 20

Multiple Choice

Two long parallel wires that are $0.30 \mathrm {~m}$ apart carry currents of $5.0 \mathrm {~A}$ and $8.0 \mathrm {~A}$ in the opposite direction. Find the magnitude of the force per unit length that each wire exerts on the other wire and indicate if the force is attractive or repulsive. $\left( \mu _ { 0 } = 4 \pi \times 10 ^ { - 7 } \mathrm {~T} \cdot \mathrm { m } / \mathrm { A } \right)$

• A) \(7.2 \times 10 ^ { - 5 } \mathrm {~N}\) repulsive
• B) \(2.7 \times 10 ^ { - 5 } \mathrm {~N}\) attractive
• C) \(2.7 \times 10 ^ { - 5 } \mathrm {~N}\) repulsive
• D) \(7.2 \times 10 ^ { - 5 } \mathrm {~N}\) attractive
• E) \(3.4 \times 10 - 5 \mathrm {~N}\) attractive
