Answer:
Explanation:
Angle of dip = 56° , magnetic field strength = 50μT
Vertical component = 50 x sin 56 = 41.45 μT
Horizontal component = 50 cos 56 = 27.96μT
New field is added in vertical downwards direction to increase the vertical component so as to increase the angle of dip . Let this field be B
total vertical field = B + 41.45
Horizontal component = 27.96
dip angle be θ
tanθ = vertical component / horizontal component
tan62 = B + 41.45 / 27.96
1.88 = B + 41.45 / 27.96
52.58 = B + 41.45
B = 11.13 μT
Since magnetic field has to be added , current should be clockwise when looked from above.
20 kg*m/s because there is 2 kg mass and 10 m/s so you can multiply.
