Concept explainers
The force per unit length exerted on the other two wires.
Answer to Problem 39P
The force per unit length exerted on the nearest wire is
Explanation of Solution
Given:
The magnitude of the current flowing in both the wires is 25 A in the upward and downward direction respectively. The distance between the third wire and the nearest one is 2.8mm.
Formula used:
Force exerted by a single wire on the other parallel single wire is
Calculation:
The force experienced in the third wire due to the nearest one is
And, the force experienced in the third wire due to the far one is
Conclusion:
The force per unit length exerted on the nearest wire is
