Two straight wires carry current of 5A opposite direction separated by a distance of 30cm. What is the magnitude of magnetic fie
1 answer:
Answer:
The magnitude of magnetic field of both wires is β= 13. 33T
Explanation:
Using the right hand rule field magnetic as the current go in opposite direction the field in the point exactly in the middle have the same direction both so
They have the same direction and the P point is the middle as the same current field can be find:
T
=13.33

(a) The lowest frequency (called fundamental frequency) of a wire stretched under a tension T is given by
where
L is the wire length
T is the tension
m is the wire mass
In our problem, L=10.9 m, m=55.8 g=0.0558 kg and T=253 N, therefore the fundamental frequency of the wire is
b) The frequency of the nth-harmonic for a standing wave in a wire is given by
where n is the order of the harmonic and f1 is the fundamental frequency. If we use n=2, we find the second lowest frequency of the wire:
c) Similarly, the third lowest frequency (third harmonic) is given by
where
L is the wire length
T is the tension
