Answer:
Explanation:
l = 200 m
i = 5 A west
B = 6 micro Tesla direction 30 degree north of east
angle between length vector and the magnetic field vector = 180 - 30 = 150 degree
Write the length and the magnetic field in the vector form
Thus, the magnitude of force is 3 x 10^-3 newton and it is directed towards negative z axis direction.
