Because it's pointing directly up, in the z direction. It has values of zero in the x and y direction. So 0i+0j+60k. The position vector tells where in space the force vector is. The force vector only gives the general direction in 3-D space of the magnitude of the force. 9 months too late, but maybe this will help someone else.
Thank you so much you're a life saver!😄
Will you get a different answer if you use vectors going the other way? And if so are both correct?
Thanks bro for your videos. They are very helpful You are great!
For the second moment, why did you put 80 under "j" (while doing cross product)? Shouldn't it be under 'k'?
So helpful thank you!
How the hell is the x 3.46i
Make sure your calculator is in degree mode and it is cos(30)×4
you saved my ass, thank you so much!
Great videos :D thanks !!
why the FORCE of B only 60k onlyyyy...helppp

GOOD explanation however we cant see the diagram or hwt you writing clearly its blurry
