Hi guys, I'm new here so thanks for any guidance...(adsbygoogle = window.adsbygoogle || []).push({});

Using vector notation, I need to find the velocity of an infinte 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 pointr= (x, y, z) which is inside the rod

(egr┴ = (√x²+y²) < radius of the rod, a )

The charge itself is not important, I simply need to find the velocityVof it.

I have a vague idea as to how to do this:

I know that the velocity is perpendicular to bothrand the z-axis, so it probably involves some sort of cross product?

Using the unit vectorkmultiplied byr/|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
