In: Physics
The projection or scalar component of a force along a line is found by:
| A. Finding the direction cosines for the force with respect to a rectangular coordinate system. | 
| B. Taking the cross product of the force and the vector representation of the line. | 
| C. Taking the scalar product of the force and the vector representation of the line. | 
| D. Finding the direction cosines for the line with respect to a rectangular coordinate system. | 
component of force is given by



So it is
C. Taking the scalar product of the force and the vector representation of the line.
