Avertical straight wire carrying an upward 24-a current exerts an attractive force per unit length of 88 x 104n/m on a second parallel wire 7.0 cm away. what current (magnitude and direction) flows in the second wire?

The current flows in the second wire is

Explanation:

Given that,

Upward current = 24 A

Force per unit length

Distance = 7.0 cm

We need to calculate the current in second wire

Using formula of magnetic force

Where,

=force per unit length

I₁= current in first wire

I₂=current in second wire

r = distance between the wires

Put the value into the formula

Hence, The current flows in the second wire is

a.) is the correct answer.

explanation:

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
