Charged Particles Moving in a Magnetic Field Ranking Task

[seto6]

Homework Statement

Five equal-mass particles (A–E) enter a region of uniform magnetic field directed into the page. They follow the trajectories illustrated in the figure.

Homework Equations

The Attempt at a Solution

i used the formula v=qBr/m
got the following "A,B,C=E,D" apparently this is wrong i do not know why..i find this question contradicting because it says at first "Five equal-mass particles" but the five masses are not the same because the electron is A and proton are the rest. could someone help me

 

[seto6]

got it . it is not solvable

What do you want to rank the particles upon?

 

[RoyalCat]

A charged particle doesn't have to be either an electron or a proton. You can have two particles with equal mass, same magnitude of charge, but different sign of charge, like an electron and a positron (Same mass as an electron, but +e charge)

Or you could be discussing macroscopic particles for that matter, onto which you can impart any charge you'd like.

By the way, what is the question here? What are the charge signs and relative velocities of all the particles?

understand this question better

I would like to provide a response to the content by first clarifying that the five equal-mass particles mentioned in the problem refer to the mass of each individual particle, not the masses of the different particles being compared. The electron (A) and proton (B-E) have different masses, but within each group, the particles are considered equal in mass.

Moving on to the solution attempt, the formula used, v=qBr/m, is correct for calculating the velocity of a charged particle moving in a magnetic field. However, it is important to note that the direction of the magnetic field is into the page, which means the direction of the velocity vector will be perpendicular to the page. This may explain why the solution obtained, "A,B,C=E,D," is incorrect. In addition, the mass of the particles and their charge (q) also play a role in determining their velocities.

Without knowing the specific values for the particles' mass and charge, it is difficult to provide a more accurate solution. However, it is important to consider the direction of the magnetic field and the properties of the particles when solving this type of problem. Additionally, it may be helpful to draw a diagram to visualize the motion of the particles and determine the correct ranking.
