Q. A right handed screw will advance in the direction of the positive $Z$-axis, if
Vector Algebra
Solution:
When the positive $X$-axis is rotated counterclockwise into the positive $Y$-axis, a right handed (standard) screw would advance in the direction of the positive Z-axis.
In a right handed coordinate system, the thumb of the right hand points in the direction of the positive Z-axis when the fingers are curled in the direction away from the positive $X$-axis toward the positive $Y$-axis.
