Quick oral answer
The direction of force experienced by the alpha particle is into the page, as determined by the right-hand thumb rule.
Common mistakes
- 1.confusing the direction of force with the direction of the magnetic field
- 2.not using the right-hand thumb rule correctly
Analysis and explanation
The right-hand thumb rule is used to determine the direction of force experienced by a charged particle in a magnetic field. The rule states that if the thumb points in the direction of the magnetic field, the fingers will curl in the direction of the force experienced by the particle. In this case, the alpha particle is positively charged, so the direction of force is in the direction of the thumb when the fingers are curled in the direction of the magnetic field.
Interesting facts
The right-hand thumb rule is a useful tool for determining the direction of force experienced by a charged particle in a magnetic field.
The direction of force experienced by a charged particle in a magnetic field depends on the charge of the particle and the direction of the magnetic field.
