Thank you for your help! I confused the two equations, sorry. My answers now: A: -B B: -(pi+1)B The current is NI, which is 2I? So the loop’s magnetic field is μ2I/2R= μI/R. C: +(+pi-1)B The wires don’t meet, so the current stays the same? D: +(2+1/2pi)B E: +pi.B/2 F: +(1/4pi+1)B G...

Homework Statement The wires below are infinitely long and some of them are with loops and semi loops. The current I is constant. What is the magnetic field in point O, when R is the distance from it? Questions: In F, E and H, the magnetic field exerted by the terminal infinitely long...

So in B I use E=k * Q/(D-r)^2 with r, the distance I found in A. Thanks again!

Thanks :) How would you find the distance from point P to the particle q? I've thought of another way: maybe use a new variable such as x, and then subtract x from D, as in E=k * Q/x^2 ; distance from p= D-x? I'm unsure.

Homework Statement An infinite, charged plane/plate has a uniform positive charge density of σ. Another positively charged particle is found at a distant of D from the plane. In point P, positioned between the two, the electric field equals 0. A. What is the distance between point P and...

Homework Statement The slop has friction. Variables: m1=4kg , m2=2kg, m3=8kg μ (coefficient) = 0.1 α=30° 1. What is the acceleration of the system? 2. Calculate the tension of the rope between m1 to m2 and between m2 to m3. Homework Equations Newton's second law and free...
