Question

Look at the expression for e/m and match the equipment parts and the parameters in the formula. Note there could be multiple parameters "buried" a single piece of equipment and vice versa (but don't over-think it).

Look at the picture below and match the numbered parts of the apparatus with their function. alm OF THE ELECTRON APPARATUS OFF Accelerating Voltage Coil Current Adjust cument ON Adjust Voltage 2 Evacuated glass bulb 6 ON/OFF switch 4 Electron speed control and display 5 Magnetic field control and display 3 Glass ruler to measure electron trajectory curvature 1 Coils producing uniform magnetic field

Explanation / Answer

1. The radius R

2) Is the gun for charged particles so controls N

3) The place at which the charge is suspened freely i.e. r

4) Control for applied voltage V

5) Control for coil current I

6) on/off switch so controls the magnetic field i.e. mu_0
