In a hypothetical fusion research lab, high temperature
Chapter , Problem 79(choose chapter or problem)
In a hypothetical fusion research lab, high temperature helium gas is completely ionized and each helium atom is separated into two free electrons and the remaining positively charged nucleus, which is called an alpha particle. An applied electric field causes the alpha particles to drift to the east at 25.0 m/s while the electrons drift to the west at 88.0 m/s.The alpha particle density is 2.80 $ 1015 cm#3 . What are (a) the net current density and (b) the current direction?
