Presumably you are intended to assume that say, the particle is massive and charged? If that is the case which of those forces would produce such motion.Ellie said:I got a question from my exam. We are given the name of three fields; electric field, magnetic field and gravitational field. A charged particle is placed in a field, but no force will act on it if it's stationary or moving in any direction. What field is the particle placed in?

If it is the right combination of electric and a gravitational fields can do the job at rest.
When it moves, its energy increases by a factor 1/sqrt(1-v^2) but so does its charge.
So the solution is still valid.
The charge is a Lorentz invariant, and does not change with motion.my2cts said:When it moves, its energy increases by a factor 1/sqrt(1-v^2) but so does its charge.
A magnetic field is a region in space where a magnetic force can be felt. It is created by moving electric charges, such as those found in magnets or electric currents.
An electric field is created by stationary electric charges, while a magnetic field is created by moving electric charges. Additionally, electric fields interact with and can be shielded by conductive materials, while magnetic fields can pass through most materials.
Magnetic and electric fields are closely related and can even be considered different aspects of the same phenomenon. They can be converted into one another and are both governed by Maxwell's equations.
A gravitational field is created by massive objects and affects all objects with mass, while magnetic and electric fields only affect objects with electric charges. Gravitational fields also follow Newton's law of universal gravitation, while magnetic and electric fields follow different laws.
Yes, magnetic and electric fields can be manipulated and controlled using various methods such as changing the strength of the source, altering the orientation of the field, or using materials with specific magnetic or electric properties. However, gravitational fields cannot be manipulated in the same way.
