Force per unit length on the wire in the bottom left hand corner.

AI Thread Summary
The discussion revolves around calculating the force per unit length on a wire located in the bottom left corner of a square configuration with four identical currents of 13 A. The side length of the square is 64 cm, and the force is to be determined in both x and y components. The relevant equation used for the calculation is F = (μ₀ * i₁ * i₂) / (2 * π * d). An initial attempt at the solution yielded a force value of 1.095E-4, but the user expressed uncertainty about the correctness of this answer. The thread emphasizes the need for accurate calculations and understanding of the forces involved in this current configuration.

1. Homework Statement [/b]
Suppose in the figure that the four identical currents i = 13 A, into or out of the page as shown, form a square of side 64 cm. What is the force per unit length (magnitude and direction) on the wire in the bottom left hand corner? (N/m) Take the positive y direction as up and the positive x direction as to the right.
What is the magnitude of the force per unit length?

(diagram is in following post)

What is the x component of the force per unit length?

What is the y component of the force per unit length?


Homework Equations



F= muo*i1*i2/2*pi*d

The Attempt at a Solution


F= 1.26E-6 * 7A * 7A/ 2*pi* sqrt(2*.64m) = 1.095E-4

i do not know if i am doing this right at all...but this answer is wrong for the the first part..

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
