Show hintHide hint
Think about the geometric representation.
Question 2.
What does the right-hand rule help determine?
Show hintHide hint
Recall how you would physically apply your hand.
3Question 3.
What describes the resultant vector from a cross product?
- Collinear to the original vectors
- Perpendicular to both original vectors
- Parallel to the original vectors
Show hintHide hint
Think about the geometric interpretation.
4Question 4.
True or False: The cross product's magnitude is highest when the vectors are perpendicular.
- True
- False
Show hintHide hint
Consider the sine function values.
Question 5.
Given three vectors A = (2, -1, 4), B = (3, 3, 1), and C = (1, 0, 2), find A × (B × C).
Show hintHide hint
Remember vector identities and use distributive properties.
Question 6.
In a physics experiment, a force vector F = (5, 0, 0) is applied at a point on a lever arm R = (0, 3, 4). Calculate the torque produced by this force around the pivot point.
Show hintHide hint
Use the cross product to find torque, ensuring vector order matters!
