Homework Statement
Figure 21.13a shows the bubble-chamber tracks resulting from an event that begins at point A.
At this point a gamma ray (emitted by certain radioactive substances), traveling in from the left,
spontaneously transforms into two charged particles. There is no track from the gamma ray
itself. These particles move away from point A, producing the two spiral tracks. A third charged
particle is knocked out of a hydrogen atom and moves forward, producing the long track with
the slight upward curvature. Each of the three particles has the same mass and carries a charge
of the same magnitude. A uniform magnetic field is directed out of the paper toward you. What
is the sign ( +or - ) of the charge carried by each particle?
According to the book the answer is B but i don't understand why,and how to apply the hand rule
Homework Equations
no equations
The Attempt at a Solution
i know i have to use the first right hand rule,and i know the thumb represents the velocity,the rest of the fingers the magnetic field and the force is perpendicular to the palm
