Question

Hello, I have been working on this problem for a while now and haveno idea what to do. I was hoping someone could at least do thefirst step and find the current. - There is an infinitely long line fo charge with chargdensity lamba and a charge Q is located a distance r from thelinear charge density. I found the electric field. - You now move at a velocity v in the direction of the-x-axis. In this frame of reference, the linear charge density ismoving in the direction of +x-axis with velocity v along with thecharge Q. a) What is the current due to the relative motion of thelinear charge density with respect to your frame ofreference? b) What is the magnetic field at a distance r from thiscurrent in this new frame of reference? Thanks in advance - There is an infinitely long line fo charge with chargdensity lamba and a charge Q is located a distance r from thelinear charge density.

Explanation / Answer

the average current I=Q/t Q=nAxq=nAvtq so I=nqvA the number of charge multiply by the velocity times thearea which they go through this is the basic way to find current hope it helps
