Question

state right hand screw rule and right hand curl rule​

Answer 1

Explanation:

Right hand rule -

Imagine the axis of rotation to be held in right hand with the fingres curled around it and thumb outstretched. If the curled fingers give the direction of motion of a particle performing circular motion, then the direction of outstretched thumb gives the direction of angular displacement vector.

Screw rule

The right hand screw rule can be used when a direction must be determined based upon a rotational direction, or vice versa. ... 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.

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.

Right hand thumb rule:- Here the fingers of the right hand are curled from Vector A to B. Then the direction of erect thumb will give the direction of C.
