Two long, straight wires are parallel and 10 cm apart.One carries a current of 2.0 A, the other a current of 5.0A. (a) If the tw
lubasha [3.4K]

Answer:

Explanation:

Given

Distance between two wires d=10 cm

Current value i_1=2 A

i_2=5 A

(a)If current flows in opposite direction

When current Flows in opposite direction the two wires will repel each other

Force due to current carrying wire F=\frac{\mu _0i_1i_2}{2\pi r}

F_{12}=F_{21}=\frac{\mu _0\times 2\times 5}{2\times \pi \times 0.1}

F_{12}=\frac{4\pi \times 10^{-7}\times 2\times 5}{2\pi \times 0.1}

F_{12}=2\times 10^{-5} N (Repulsive Force)

(b)If current is flowing in the same direction

When direction of current is same then force will be attractive in nature

F_{12}=F_{21}=\frac{\mu _0i_1i_2}{2\pi r}

F_{12}=\frac{4\pi \times 10^{-7}\times 2\times 5}{2\pi \times 0.1}

F_{12}=2\times 10^{-5} N (attractive Force)

What is the model size to actual size
Murljashka [212]

Answer:

You have to divide your real measurement to the model. For example, if your real measurement is 5m and your model is 20cm, divide 5/20 =1/4 and that means the ratio would be 1:4.
