## Homework Statement

1.Sketch a diagram of the atom He3, using the appropriate quarks and leptons.

2 The charge-to-mass ratio of the pion was determined in 1. The charge-to-mass ratio of the electron is 1.76 x 10^11 C/kg.

a) Based on this info, predict which particle has a greater mass- the electron of the pion . Justify your answer by referring to the charge-to-mass ratio.

b) Use the value of the elementary charge (e = 1.6 x 10^-19C) to calculate the mass of the pion in kg. Compare the mass of the pion to the mass of the electron.

## Homework Equations

q = q/m x m

## The Attempt at a Solution

1. No problems, just stated question to illustrate entire problem

2a) I predict the He3 particle will have more mass- it consists of 2 protons, 1 neutron and 2 electrons

2b) mass of electron = charge/ charge to mass ratio

= (1.6 x 10^(-19) C)/(1.76 x 10^11 C/kg)

= 9.09 x 10-31 kg

It's the pion charge-to-mass ratio I'm having troubles with. Between the quarks and leptons- it is a neutral atom, therefore dividing the charge by the mass is 0

I feel like I've been at this too long, and I'm missing a basic point here.

Please help
