Question #c2c8e

Answer 1

61.7N, pointing west

Explanation:

Magnetic for is a vector quantity:
`vecF=IveclxxvecB`

`F=ILBsintheta`

`F=6180A*130m*82.2xx10^-6T*sin(69) =61.7AmT=61.7N`

Apply the right hand rule by curling the finger of the right hand from north downward to ground, i.e., from `vecl` to `vecB`. In doing so, the thumb is pointing to the west.

Thus, the 61.7 force pushes the power line westward.
