N a lab, two pieces of cellophane tape are placed on a lab table. They are quickly ripped off the lab table. Which would you predict would happen if the two pieces of tape were brought near each other?
A) The two pieces of tape would repel each other.
B) The two pieces of tape would attract each other.
C) There would be no attraction or repulsion between the pieces of tape.
D) There is no predictable result as the two pieces of tape are brought near each other.

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
