Answer:
The length of the wire is 2.86 m
Explanation:
Given:
Current
A
Magnetic field
T
Force
N
Angle between wire and magnetic field
46°
The magnetic force on the current carrying wire is given by,
![F = BIl\sin \theta](https://tex.z-dn.net/?f=F%20%3D%20BIl%5Csin%20%5Ctheta)
Where
length of wire
![l = \frac{F}{BI \sin 46}](https://tex.z-dn.net/?f=l%20%3D%20%5Cfrac%7BF%7D%7BBI%20%5Csin%2046%7D)
![l = \frac{9.4 \times 10^{-5} }{6 \times 10^{-5}\times 0.76 \times 0.7193}](https://tex.z-dn.net/?f=l%20%3D%20%5Cfrac%7B9.4%20%5Ctimes%2010%5E%7B-5%7D%20%7D%7B6%20%5Ctimes%2010%5E%7B-5%7D%5Ctimes%20%200.76%20%5Ctimes%200.7193%7D)
m
Therefore, the length of the wire is 2.86 m
The time required to travel that distance at the given speed is determined as 15.84 seconds.
<h3>Time of motion</h3>
The time of motion of the person is calculated as follows;
Distance = speed x time
time = distance/speed
where;
- distance = 500 m = 0.31 mile
time = (0.31 mile)/(70 mph)
time = 0.0044 hr = 15.84 seconds
Thus, the time required to travel that distance at the given speed is determined as 15.84 seconds.
