Question

Es The motion of maglev, or magnetic levitation, trains is generated by using electromagnets to lift and propel the train. If a

maglev train is accelerating at 10 km/hr/sec, what statement about the forces acting on the train is accurate?
A)
Friction exceeds the applied force
The applied force is greater than friction.
There are no vertical forces acting on the train.
The forces acting on the train are in equilibrium since acceleration is
constant
Submit

Answer 1

The applied force is greater than friction.

Step-by-step explanation:

The applied force is greater than friction. Acceleration can only occur when forces are unbalanced. Since the train has positive acceleration, applied force is greater than friction. The vertical forces of gravity and support force are in equilibrium.

Answer 2

"There are no vertical forces acting on the train" statement about the forces acting on the train is accurate.

Answer: Option C

Step-by-step explanation:

Maglev or magnetic levitation work on the principle of complete deflection of magnetic line of forces around a superconductor material. So, the deflection or repulsion of magnetic flux will support the other object to remain floated above the track which is composed of a superconductor.

As there is only magnetic force acting on the train, the object or train will be moved forward by the deflection of magnetic flux lines on the track. Thus there would be no vertical forces acting on the train so the journey will be smooth due to constant acceleration.
