Charge to Mass Ratio of Pi-Particle: Calculate & Compare to Electron

AI Thread Summary
The discussion focuses on calculating the charge to mass ratio of the pion particle in helium, comparing it to that of the electron. The charge to mass ratio of the electron is established at 1.76 x 10^11 C/kg, with the elementary charge noted as 1.6 x 10^-19 C. Participants are asked to predict which particle, the electron or pion, has a greater mass based on these ratios and to calculate the mass of the pion in kilograms. The conversation highlights the need for guidance on how to approach these calculations, particularly for part B of the problem. Ultimately, the thread underscores the complexities of particle physics calculations and the importance of understanding charge and mass relationships.

My last question that needs to be completed today..

Determine the charge to mass ratio of the (pi)- particle of He (3 nucleons) 2 electrons. The charge to mass ratio of the electron is 1.76 x 10^11 C/kg

Equation:
q/m = charge to mass ratio
all sub atomic particles have a charge of +/- (1.6 x10^ -19C)

a)predict which particle has a greater mass - the electron or pion. Justify your answer referring to charge mass ratios

b)Use the value of th elementary charge (1.6x10^-19 C) to calculate the mass of the pion particle in kilograms. Compare the mass of the pion to the mass of the electron..

Can someone point me in the right direction i have no clue where to begin.

nevermind figured it out.
 
I have a similar question that I can't figure out part B to, does anyone know how?
 

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...
