Question
Please help me with these two questions
A bubble chamber is a vessel with a uniform magnetic field running through it filled
with a superheated transparent liquid (most often liquid hydrogen) used to detect
electrically charged particles moving through it. It was invented in 1952 by Donald A.
Glaser, for which he was awarded the 1960 Nobel Prize in Physics.
Here is a photograph obtained in a bubble chamber, showing various charges circling
around because of the magnetic field:
Which of the following statements is false?
Hint: Use the formula you found in the last question to help you with this question.
O Particles with positive charge will circle in one direction (perhaps clockwise)
while particles of negative charge will circle in the opposite direction (perhaps
counterclockwise).
O Heavier charges would have a larger radius of curvature.
Particles with a larger charge would have a larger radius of curvature.
O Faster particles would have a larger radius of curvature.
Increasing the magnetic field strength in the bubble chamber would result in a
smaller radius of curvature for the particles.
O Neutral particles would pass straight through the chamber without bending due
to the magnetic field.

B
If the loop was initially at rest and floating in space and was free to move in any way
whatsoever, how would it move?
The triangle would remain still.
The triangle would start moving to the right.
The triangle would start moving to the left.
The triangle would start moving up.
The triangle would start moving down.
The triangle would start out of the screen (towards you).
The triangle would start into the screen (away from you).
The triangle would remain in place, but would start to spin in some direction.
