Determine the x,y,z components of a 100N force passing from the origin through the point (2,-4,1). Express the vector in terms of unit vectors Î,j,kˆ.

Dear sanket

As the vector passes through origin and the point (2,-4,1) the unit vecor along this dirction is

2 i - 4j + k/√21 (Unit vector can be be obtaoned by dividing the vector by its mod)

Since the force has magnitude 100N

the force vector becomes magnitude * unit vector =100* 2 i - 4j + k/√21

ALL THE BEST
