After working on this problem for more than 4 hours and reading about the topic in different books, I decided to ask here for help since I do not seem to have a clue.

"A counting tube for a particle accelerator consists of a thin-walled metal tube and a wire that goes along the tube's center axis. The tube has a radius of 12 mm and the wire of 12 X 10^-6 m. Between the tube and the wire there is a current of 1000 volts.

a) Calculate the factor of which the force acting on a particle increases on its way from the tube's wall to the wire.

Answer: 400 times

I have problems to make a connection between the 1000 volts and the electric field with which I could calculate a force (according to Gauss).

What could I start with?

Any help will be appreciated!
