When electron and proton have equal momentum enter normal to uniform magnetic field?
An electron and a proton with equal momentum enter perpendicularly into a uniform magnetic then. a The path of proton shall be more curved than that of electron. b The path of proton shall be less curved turn that of electron.
What is the ratio of radii of two paths when an electron and a proton enter at right angles to a uniform field?
So it will be one by 1840. Okay, so if velocity is same, the ratio will be one by 1840.
What happens when a proton enters a uniform magnetic field?
A proton enters a uniform magnetic field that is perpendicular to the proton’s velocity. The velocity of the proton changes direction but the magnitude (speed) doesn’t change. Thus the kinetic energy stays the same.
What happens to the momentum of a charged particle in a uniform magnetic field?
So, when the velocity of the particle is constant its energy will also remain constant. Thus, we can say, when a charged particle moves perpendicular to the uniform magnetic field, then the momentum changes while the total energy remains the same.
When a charged particle enters in a uniform magnetic field then its kinetic energy?
The magnetic field does no work, so the kinetic energy and speed of a charged particle in a magnetic field remain constant. The magnetic force, acting perpendicular to the velocity of the particle, will cause circular motion.
When any moving charge enters in a magnetic field perpendicularly then its path will be?
When a charged particle enters a magnetic field at a direction perpendicular to the direction of motion, the path of the motion is circular.
What is the ratio of radii of two paths when an electron and a proton?
ANSWER. The ratio of radii of two paths when an electron and a proton enter at right angles is 1:1.
Why does a proton move in a circle in a magnetic field?
Protons in giant accelerators are kept in a circular path by magnetic force. Magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected, but not the speed.
When a magnetic dipole is placed in a uniform magnetic field it experiences?
If a dipole is placed in a uniform magnetic field, it experiences a torque but no force. When a dipole is placed in a non uniform electric field, it experiences a non zero net force as well as torque.
What is the unit of E B?
SI electromagnetism units
| SI electromagnetism units v t e | ||
|---|---|---|
| Symbol | Name of quantity | Unit name |
| E | electric field strength | volt per metre |
| D | electric displacement field | coulomb per square metre |
| ε | permittivity | farad per metre |
When a charged particle moves in a uniform magnetic field which of the following always remain constant?
Another way to look at this is that the magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected but not the speed. Figure 11.4.
What happens when electron and proton enter a uniform magnetic field?
An electron and a proton with equal momentum enter perpendicularly into a uniform magnetic then. An electron and a proton with equal momentum enter perpendicularly into a uniform magnetic then. (a) The path of proton shall be more curved than that of electron.
What is the radius of a proton in a magnetic field?
Since mass of proton is approx, 2,000 X the mass of an electron, the radii would be of the same factor as well. Radius of particle trajectory in a uniform field is equal to m*v/ (q*B) in case velocity vector is perpendicukar to the magnetic field direction.
Why do electrons and protons move on different radii circles?
Since both – the electron and the proton entered the same region of uniform magnetic field with same velocity and they contain charges of equal magnitudes as well, so it is only their unequal masses that will cause them to move on different radii circles. One having the greater mass would move on a greater circle.
How do you find the mass of an electron and proton?
An electron and a proton of equal linear momentum enter in the direction perpendicular to uniform magnetic field. If the radii of their circular paths be re and rp, respectively, then rr/rp is equal to me = mass of electron, mp = mass of proton. POPULAR CHAPTERS BY CLASS class 5
