I believe that I have found the correct force vector:
However, I am not sure how to figure out how to show that it points from the object towards the point
Any help would be greatly appreciated.
Find the vector and parametric equations for the line segment connecting P to Q.
P(0, - 1, 1), Q(1/2, 1/3, 1/4)
= () for
no longer satisfies the triangle inequality?
I know that in one dimension, the norm is just an absolute value, and the triangle inequality holds. I could take two unit vectors.
For example, = (0,1,0) and = (2/3.2/3.1/3)
But I don't really know how I can put the unit vectors in the sum above to show that
+ does not hold.
