# Tower Guy Wire The guy wire supporting a 100-foot lower has a tension of 550 pounds. Using the distance shown in the figure, write the component form of the vector F representing the tension in the wire. To determine
The component form of the vector F that represents the tension in the wire.

Explanation

Given: The height of the tower is 100-foot and the tension 550 pounds as shown in figure below

Explanation: Consider the point P on the groundas seen on the figure, the co ordinates of P are (75, -50, 0) and let the top of the tower be Q and coordinates of it be (0, 0, 100).

PQ=075,0+50,1000=75,50,100

Since F is parallel to  PQ . So,

F=c.PQ, where  c be a scalar

Therefore,

PQ=075,0+50,1000=75,50,100

And

F</
