Consider the case in which a positively charged particle is moving in a uniform magnetic and electric fields perpendicular to each other. The particle velocity v is perpendicular to both fields (as is shown in the figure below). What is the magnitude of the velocity v for which the sum of the two forces, i.e. magnetic and electric, on the charged particle is zero? 1* É × × × x x x xx x x x x x V F B Bin x x x!x x x x x x x x x x x x x x x x x xi x x x x x x x + + +

Consider the case in which a positively charged
particle is moving in a uniform magnetic and
electric fields perpendicular to each other. The
particle velocity v is perpendicular to both fields (as
is shown in the figure below). What is the
magnitude of the velocity v for which the sum of
the two forces, i.e. magnetic and electric, on the
charged particle is zero?
