Answer:
Magnitude of the force is 2.135N and the direction is 41.8° below negative y-axis
Explanation:
The stiff wire 50.0cm long bent at a right angle in the middle
One section lies along the z axis and the other is along the line y=2x in the xy plane
tan θ = 2
Therefore,
slope m = tan θ = y / x
Then length of each section is 25.0cm
so, length vector of the wire is
And magnetic field is B = (0.318T)i
Therefore,
Magnitude of the force is
Direction is
Magnitude of the force is 2.135N and the direction is 41.8° below negative y-axis
Answer:
ΔK = 24 joules.
Explanation:
Δ Work done on the object
Work is equal to the dot product of force supplied and the displacement of the object.
* Δ
Δ can be found by subtracting the vectors (7.0, -8.0) and (11.0, -5.0), which is written as Δ
= (11.0 - 7.0, -5.0 - -8.0) which equals (4.0, 3.0).
This gives us
