Which of the following acts in accordance with right hand screw rule?a...
Explanation:
The right-hand screw rule is a method used to determine the direction of a vector in three dimensions. It is a mnemonic device that helps to remember the direction of the cross product of two vectors.
Axial Vector:
An axial vector is a vector that is perpendicular to the plane formed by two other vectors. Axial vectors are also known as cross products. When two vectors A and B are crossed, the result is a third vector C, which is perpendicular to both A and B. The direction of the axial vector is given by the right-hand screw rule.
Right Hand Screw Rule:
The right-hand screw rule states that if you point your right thumb in the direction of vector A and curl your fingers towards vector B, then the direction in which your extended fingers point is the direction of the axial vector C.
Example:
For example, if vector A is in the positive x-direction and vector B is in the positive y-direction, then the direction of the axial vector C is in the positive z-direction.
Polar Vector:
A polar vector is a vector that has a magnitude and direction. Examples of polar vectors include velocity, force, and acceleration. The direction of a polar vector is given by the angle it makes with a reference axis.
Displacement Vector:
A displacement vector is a vector that describes the change in position of an object. It has both magnitude and direction. The direction of a displacement vector is given by the direction of the change in position.
Position Vector:
A position vector is a vector that describes the position of an object relative to a reference point. It has both magnitude and direction. The direction of a position vector is given by the direction from the reference point to the object.
Therefore, the option that acts in accordance with the right-hand screw rule is option B, which is the axial vector.
