So if you have a question with a B-field you need any speed given from the particles who entering in this field.
Who can I find this speed? Thanks.
Bert said:I try this but I fail so:
[tex]\frac{1}{2}m . v^2=U[/tex]
then we have
[tex]1,602 \ . \ 10^{-19} \ . \ 1 . \ 10^5=1,602 \ . \ 10^{-14}= \frac{1}{2} 10^{-27}.v^2 [/tex]
so [tex]v[/tex] must be [tex]\sqrt{ \frac{2 \ . \ 1,602 . 10^{-14} } {10 ^{-27} } }[/tex]
is this correct?
The equation for finding the speed of particles in a magnetic field is v = qB/m, where v is the speed, q is the charge of the particle, B is the strength of the magnetic field, and m is the mass of the particle.
The direction of the particle's velocity in a magnetic field can be determined using the right-hand rule. If you point your thumb in the direction of the particle's velocity, and your fingers in the direction of the magnetic field, the direction your palm faces will be the direction of the particle's velocity.
Yes, the speed of a particle in a magnetic field can change if the strength of the magnetic field or the charge/mass of the particle changes. The direction of the particle's velocity can also change if the direction of the magnetic field changes.
Knowing the speed of particles in a magnetic field is important in various fields of science, such as particle physics and astrophysics. It can help us understand the behavior of charged particles in different environments and how they interact with magnetic fields.
Yes, there are many real-world applications of finding the speed of particles in a magnetic field. Some examples include particle accelerators, MRI machines, and the study of Earth's magnetic field and its effects on charged particles in space.
