Magnetic Force: charged particles trajectories in a magnetic field

In this Form you will work with pictures taken from a real nuclear physics experiment. Low energy pions are sent in a chamber filled with Helium gas (2protons + 2 neutrons). In the image below you can see the collision of the pion with one Helium nucleus. The incoming pion is highlighted in the image and is negatively charged. As you can see, the tracks of the particles are curved trajectories. This is due to a magnetic field B in which the whole chamber is embedded.

Taking into account the Magnetic Force determine the sign of the charges of the particles related to tracks 1 and 2. *

Track 1 - positive charge; Track 2 - negative charge

Track 1 - positive charge; Track 2 - positive charge 2

Track 1 -negative charge; Track 2 - negative charge

Track 1 - negative charge; Track 2 - positive charge

Can you figure out what particles are probably related to track 1 and 2? *

In the collision the Heilum nucleus gains momentum and recoils. Can you recognize the recoiling Helium nucleus in the picture of the first question? Try to explain the reasoning behind your answer. *

Working on the image of the first question, determine the direction of the Magnetic field acting on the particles moving in the chamber. *

Parallel to the trajectory of the incoming pion

Perpendicular to the plane of the picture and pointing inwards to the plane of the image

Along the plane of the picture and perpendicular to the velocity of the incoming pion

Perpendicular to the plane of the picture and pointing outwards to the plane of the image

Along the plane of the picture and in the bottom-top direction

We are in the same situation as before. A negative pion is sent against Helium nuclei. But in this occasion, we have three products. Determine the sign of the tracks. *
