Question

Determine the magnitude and direction of the force between two parallel wires 35 m long and 6.0 cm   apart, each carrying 35 A in the same direction.

Answer 1

Answer:

The magnitude of the force is 0.1429 N.

Explanation:

Given that,

Current = 35 A

Distance = 6.0

Length = 35 m

We need to calculate the force

Using formula of force

$F=\dfrac{\mu_{0}i_{1}i_{2}l}{2\pi d}$

Where, d = distance

l= length

Put the value into the formula

$F=\dfrac{4\pi\times10^{-7}\times35\times35\times35}{2\pi\times0.06}$

$F=0.1429\ N$

If the current in the same direction then the conductor attract to each other

Hence, The magnitude of the force is 0.1429 N.
