Question

Question = A cloud chamber photographe shows a pair of circular tracks emerging from a common point the tracks have similar density of droplets, but curves in the opposite direction in a plane normal to the magnetic field maintains in the chamber if one of the ionising particles are established to be an electron, guess the high energy event that took place at the common point of the track.

No spam please very urgent :)

Answer 1

$\boxed{<u> </u><u>ANS</u><u>WER</u><u> </u>}$

The similarity of the two paths shows that the other charged particle has the same mass and the same magnitude of charge as that of an electron. As the tracks are curved and in opposite direction, the nature of charge and on the other particle is opposite to that of electron. This other particle is called positron.Thus, at the common point of the track, the high energy event that took place is conversion of gamma (Y) rays photon into electron-positron pair.

Answer 2

Answer:

• The similarity of the two paths shows that the other charged particle has the same mass and the same magnitude of charge as that of an electron.

• As the tracks are curved and in opposite direction, the nature of charge and on the other particle is opposite to that of electron.

• This other particle is called positron.

• Thus, at the common point of the track, the high energy event that took place is conversion of gamma (Y) rays photon into electron-positron pair.
