Two rigid rods are oriented parallel to each other and to the ground. The rods carry the same current in the same direction. The

IRISSAK [1]

To develop this problem we will apply the concepts related to the Electromagnetic Force. The magnetic force can be defined as the product between the free space constant, the current (of each cable) and the length of these, on the perimeter of the cross section, in this case circular. Mathematically it can be expressed as,

$F= \frac{\mu_0}{2\pi} \frac{I^2L}{d}$

Here,

$\mu_0$ = Permeability free space

I = Current

L = Length

d= Distance between them

Our values are,

$L = 0.67m$

$m = 0.082kg$

$d = 7.4*10^{-3}m$

$I = \text{Current through each of the wires}$

Rearranging the previous equation to find the current,

$\frac{mg}{L} = 2*10^{-7} (\frac{I^2}{d})$

$I = \sqrt{\frac{mgd}{(2*10^{-7})L}}$

$I = \sqrt{\frac{(0.082)(9.8)(7.4*10^{-3})}{(2*10^{-7})(0.67)}}$

$I = \sqrt{44377.9}$

$I = 210.66A$

Therefore the current in the rods is 210.6A

vitfil [10]

Answer:

W = 819152 J = 819.15 KJ

Explanation:

The work done by Juri can be given by the following formula:

$W = FdCos\theta$

where,

W = Work done = ?

F = Force = 200 N

d = distance = 5 km = 5000 m

θ = angle to horizontal = 35°

Therefore,

W = (200 N)(5000 m)Cos 35°

<u>W = 819152 J = 819.15 KJ</u>
