Question

right hand screw rule​

Answer 1

The right hand screw rule can be used when a direction must be determined based upon a rotational direction, or vice versa. It is best illustrated using a diagram.

The axis is 'grasped' in the right hand, the fingers curl round in the direction of positive rotation and the thumb is orientated in the positive direction. Therefore if the direction of rotation is know the fingers can be curled in this orientation and the thumb will point in the positive direction, and vice versa.

Answer 2

Right hand screw rule:- Let the first vector be A from where the right hand screw is rotated, and towards the vector B. So the direction in which the right handed screw is rotated gives the direction of C.
