are magnetic forces usually much weaker then gravitational force?
Homework Answers
No, magnetic forces on contrary are stronger than the gravitational force.
Gravitational force is weakest force in nature. But its range is unlimited & infinite.
Electric & magnetic force is equally considered as electromagnetic force which is 1034 times stronger than gravitational force. Hence a small magnet's magnetic field stronger than whole earth's gravitational force. Its range is too large.

Why is the gravitational force usually ignored in problems involving particles such as electrons and protons?...
Why is the gravitational force usually ignored in problems involving particles such as electrons and protons? a). The electric force between charged particles is much greater than the gravitational force. b).Subatomic particles are too small to experience gravitational forces. c). Charged subatomic particles only experience electric forces. d). The distances between subatomic particles are too small. e). Protons and electrons obey quantum mechanics. Gravity does not work at the quantum level.

Even though electric forces are very much stronger than gravitational forces, gravitational forces, not electric forces, can be used to understand and predict the motion of astronomical objects (such as the planets of the Solar System) because: Question options: A) the electric forces do not act through a vacuum. B) electric forces have a longer range than gravitational forces. C) electric forces have a shorter range than gravitational forces. D) most large objects are electrically neutral because they contain as...

Two forces act on a 3.20 kg object, the gravitational force and a second, constant force. The object starts from rest and in 1.20 s is displaced (4.251 - 3.301) m. Write the second force in unit vector notation. (Enter your answer in kg. m/s. Assume the gravitational force acts in the - direction.) = (18.888)i + (17.152); First, find the acceleration vector using kinematics, then substitute into Newton's second law to determine the unknown force vector. Recall that the...

10. Two forces act on a 3 kg object, the gravitational force and a second, constant force. The object starts from rest and in 2.1 s is traveling with a velocity of (20ˆi + 10ˆj) m/s. At what angle does the second force act with respect to the ˆi direction? Assume the gravitational force acts in the −ˆj direction. (the answer is 56.8 ◦)

Why does the electric force dominate at the atomic scale while the gravitational force dominates on the large scale that includes the solar system and beyond? 1.) There is no gravitational force within atoms, because the law of gravitation applies only to large objects.2.) Atoms have no net charge, making electrical forces within atoms negligible. 3.) Atomic particles have too little mass for gravitational attraction to compete with electric forces. 4.) At large distances, individual charges have essentially no effect...

The electric force is much stronger than the gravitational force
so we can often neglect gravity in electricity and magnetism. How
far does the electron of a hydrogen atom have to be removed from
the nucleus (contains only one proton) for the force of attraction
equal the weight of the electron at the surface of the Earth (g=9.8
m/s2)? Is that large compared to the size of an atom?

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.
Two forces act on a 3.20 kg object, the gravitational force and a second, constant force. The object starts from rest and in 1.20 s is displaced (4.251 - 3.301) m.
