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 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
