The discussion centers around a physics problem involving the motion of a proton in Earth's magnetic field. Participants are exploring the relationship between the proton's speed, the magnetic force acting on it, and its weight.
The discussion is ongoing, with participants sharing their calculations and questioning the correctness of their results. Some guidance is offered regarding the relationship between the forces, but no consensus has been reached on the correct speed of the proton.
Participants mention specific values for the magnetic field and the weight of the proton, indicating a focus on the application of these values in their calculations. There is an acknowledgment of potential errors in previous attempts, but no resolution has been provided.
What is the weight of the Proton? What is the expression for magnetic force as a function of the proton's speed? Equate those two forces.kevinlikesphysics said:A proton moves eastward in the plane of Earth's magnetic equator so that its distance from the ground remains constant. What is the speed of the proton if Earth's magnetic field points north and has a magnitude of 5.0 10-5 T?
i got .002 m/s but it was wrong
That is the mass of the proton (in kg). What is the weight? (ie. the downward force on the proton).kevinlikesphysics said:the weight of the proton is 1.67e-27 but i still get the wrong answer i got 2.04e-4 can you work it out for me?
