Answer:
<em>The direction of the force is towards the East.</em>
Explanation:
Using the right hand rule, the force on the current carrying conductor is east.
In the right hand rule, if the hand is held with the fingers pointed parallel to the palm representing the magnetic field, and the thumb held at right angle to the rest of the fingers representing the direction of the current, then the palm will push in the direction of the force.
In this case, the thumb is pointing downwards, with the fingers pointing north away from the body in the direction of the earth's magnetic field, the palm will push east.
Answer:
the angle must decrease to maintain balance and that the system remains motionless
Explanation:
In a system of a block in an inclined plane, using Newton's second law
X Axis Wₓ-fr = 0
Y Axis N - = 0
The equation for the force of friction is
fr = μ N
And using trigonometry for weight components
sin θ = Wₓ / W
cos θ = W_{y}/ W
Wₓ = W sin θ
W_{y} = W cos θ
We replace
Wₓ = fr
W sin θ = μ Wcos θ
tan θ = μ
If the coefficient of friction decreases the force of static friction decreases, ₓso the value of the tangent must decrease so the angle must decrease to maintain balance and that the system remains motionless or with constant speed
