A uniform magnetic field exists in the plane of paper as shown in the diagram. In this field, an electron (e⁻) and a positron (p⁺) enter as shown. The electron and positron experience forces :
A uniform magnetic field exists in the plane of paper as shown in the diagram. In this field, an electron (e⁻) and a positron (p⁺) enter as shown. The electron and positron experience forces :
Options
Official answer
The electron and positron experience forces pointing into the plane of the paper and out of the plane of the paper respectively.
Marking scheme
- 1.1 mark for correct answer
Hint
Use the right-hand rule to determine the direction of the force on the electron and positron.
Quick oral answer
The electron and positron experience forces pointing into the plane of the paper and out of the plane of the paper respectively, due to the uniform magnetic field existing in the plane of the paper.
Common mistakes
- 1.Confusing the direction of the force on the electron and positron
- 2.Not using the right-hand rule correctly
Analysis and explanation
This question requires the application of the right-hand rule to determine the direction of the force on charged particles in a magnetic field. The correct answer is option C, which states that the electron and positron experience forces pointing into the plane of the paper and out of the plane of the paper respectively.
Interesting facts
The right-hand rule is a useful tool for determining the direction of the force on charged particles in a magnetic field.
The magnetic field is uniform and exists in the plane of the paper, which means that the force on the electron and positron will be perpendicular to the plane of the paper.
