a charged particle moves across a constant (uniform) magneticfield. The magnetic force on this particle

A) changes the paricles speed but not the direction of themotion

B)changes both the particles speed and direction of motion

C) is the direction of the particles motion

D) is in the direction of the magnetic field

E) changes the direction of the particles motion

Figure P19.14a is a diagram of a device called a velocity selector, in which particles of a specific velocity pass through undeflected while those with greater or lesser velocities are deflected either upwards or downwards. An electric field is directed perpendicular to a magnetic field, producing an electric force and a magnetic force on the charged particle that can be equal in magnitude and opposite in direction (Figure P19.14b) and hence cancel. Show that particles with a speed of v=E/B will pass through the velocity selector undeflected.
