Hi guys, I'm new here so thanks for any guidance...
Using vector notation, I need to find the velocity of an infinite rod, rotating with frequency, ω, centred on the z axis. (rotating about z-axis in the anti-clockwise direction when viewed from above).
I need to give the velocity in terms of a charge the point r = (x, y, z) which is inside the rod
(eg r┴ = (√x²+y²) < radius of the rod, a )
The charge itself is not important, I simply need to find the velocity V of it.
I have a vague idea as to how to do this:
I know that the velocity is perpendicular to both r and the z-axis, so it probably involves some sort of cross product?
Using the unit vector k multiplied by r/|r| ?
I am pretty clueless with this one guys, despite it only being simple vector manipulation... Any help would be greatly appreciated!
Thanks in advance
