• The diagram below shows a bird's-eye view of four interconnected chambers. A negative charge is sent into chamber 1 at speed v. By turning on separate magnetic fields in each chamber, the charge can be made to move along the path shown and exit from chamber 4. Determine the required direction for each chamber's magnetic field. (The positive z-axis points out of the page.) Your help is greatly appreciated! options are +x,-x, +y,-y, +z,-z(in to the page, and out of the page, respectivly)
