A long current carrying hollow wire has an inner radius of 1.50 cm and an outer radius of 12.2 cm. The current in the wire is 5.00 A. Find the magnetic field at a distance 8.20 cm from the center of the wire.

In the figure provided, an electron with speed v? = 1.4610⁷ m/s travels between two parallel charged plates. If the plates are separated by a distance d? = 2.10 cm and are charged by a 270. V battery, what magnetic field strength is required to allow the electron to pass between the plates without being deflected?
