Curvature radius of alpha and beta particles

AI Thread Summary
The discussion focuses on calculating the curvature radius of alpha and beta particles in a magnetic field. Both particles have a kinetic energy of 35 keV and are subjected to a 1.1T magnetic field, moving perpendicular to it. The user calculates the velocities of the beta particle (electron) and alpha particle (helium nucleus) using their respective masses and kinetic energy. However, they express confusion about how to apply these figures to find the curvature radius using the relevant equations. The conversation highlights a common struggle with mastering physics concepts related to particle motion in magnetic fields.

Homework Statement


An alpha particle and beta particle, each with kinetic energy 35keV , are sent through a 1.1T magnetic field. The particles move perpendicular to the field.


Homework Equations



no idea.

The Attempt at a Solution



theres nothing on curvature radius in my textbook. from what i can find on the internet it has something to do with the velocity of each of the particles which i can find using the kinetic evergy and relevant masses.
a beta particle is just an electron, which has mass 9.1094*10-31, using the given energy, gives a velocity of 1.1*108m/s

an alpha particle is a helium nucleus, with mass 6.6447*10-27
giving a velocity of 1.299*106m/s

but i got no idea what to do with the figures..

mv^2/r = qvB
mv = qrB
sqrt(2mE) = qrB

word. thanks bruh.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
