Sarah and Julie mixed sand and salt. They then added water to the mixture. How will we separate the sand from the salt now? That’s easy, said Julie the salt has dissolved in the water, and the sand has not. Just pour the water off. Where in the Venn diagram would the sand/salt/water fit? A
B
C
D

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
