The train is supported by magnetic repulsion forces exerted in the direction perpendicular to the track. Motion of the train in the transverse direction is prevented by lateral supports. The 20,000-kg train is traveling at 30 m/s on a circular segment of track with radius R = 150 m, and the bank angle of the track is 40°. Determine the magnitude of the train's total acceleration (in m/s2). Answer value.

If an electric force is a force of attraction or repulsion between charged particles and magnetic...
If an electric force is a force of attraction or repulsion between charged particles and magnetic force is a force of attraction between magnetized materials. What is the difference between magnetic force and electromagnetic force? How come electromagnetic force stick atoms together? Why do atoms have electromagnetic force?

1- Explain what the center of mass/gravity is. Can it move? Why does its location matter? 2- Define angular velocity, angular acceleration, period, frequency, moment of inertia, centripetal acceleration, and angular momentum. 3- . How does angular velocity relate to linear velocity? How does angular acceleration relate to liner acceleration? 4- Compare and contrast ‘uniform circular motion’ with ‘nonuniform circular motion

Electromagnetic forces are responsible for holding atoms together. Electromagnetic force has both electric and magnetic effect. The protons will attract the electrons this is the electric effect, right? But what is the magnetic effect here? SInce magnetic force is a force of attraction between magnetized materials.

1) Strength of the electric force The earth and the moon exert attractive gravitational forces on one another according to Newton's law of gravitation. However, since the earth and the moon are electrically neutral (that is, the net charge of each planet is zero), they do not exert electrical forces on one another. Assume now that someone (aliens) removes some number N of electrons from both the earth and the moon, so that the two bodies now exhibit electrical repulsion...
