Question
The screw rule is used by showing the fingers of
- Right leg
- Left leg
- Left hand
- Right hand
Hint:
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.
The correct answer is: Right hand
- Right hand screw rule - Let the first vector be A from where the right hand screw is rotated, and it is rotated towards the vector B. So the direction in which the right handed screw is rotated gives the direction of C (product).
