To find:
Whether the orientation of the vectors are physically reasonable.
Answer to Problem 1Q
Solution:
The orientation of vectors in figure (b) are the only physically reasonable vectors.
Explanation of Solution
1) Concept:
We can use the right hand rule to find the direction of force. For the possible orientation, we must have three vectors mutually perpendicular. From this, we can predict whether the orientation of the vectors is physically reasonable or not in the given figures.
We know that
2) Given:
We are given different orientation of vectors.
3) Calculations:
For fig. (a) Orientation of vectors is not possible because velocity
For fig. (b) Orientation of vectors is possible because force
For fig. (c) Orientation of vectors is not possible because
Conclusion
Using the right hand rule we can find the direction of force, and it must be perpendicular to both velocity and magnetic field.
