A force is given in the vector form, passes thru the point P whose coordinates are [1,2,2] in a cartesian coordinate system and are the unit vectors in the x,y and z directions respectively. Q is a point whose coordinates are [4,3,6].
i)Find the vector QP
ii)find the maqnitude the moment of the force about the point Q.
iii)Find the unit vector in the direction of the moment...
If its possible to sketch a diagram too would be great...I just cant understand VECTORS!
