The accelerating voltage is Vacc$=232$ V

The deflecting voltage is Vdef $=22$ V

The length L of the deflecting plates is $1\mathrm{.}99$ cm

The separation d between the deflecting plates is $4$ mm

The distance D from the deflecting plates to the screen is $13\mathrm{.}6$ cm

vx$=9\mathrm{.}030$E$06$

The Vertical Velocity vy

What is the vertical velocity vy of the electron upon leaving the deflection plates?

Choose the correct statement from the list below.

Increasing Vacc decreases vy$,$ while increasing Vdef increases vy$.$

Increasing Vacc increases vy$,$ while increasing Vdef decreases vy$.$

vy does not change when you vary Vdef.

vy depends only on Vdef so changing Vacc has no effect on vy$.$

Remember: The vertical speed vy depends on how long the electron is between the deflecting plates. What happens if you increase Vacc?

The Deflection Y

What is the resulting deflection Y seen on the screen?

You have a formula for how Y varies with the voltages Vdef and Vacc.

Choose the correct statement from the list below

Increasing Vacc decreases Y $,$ while increasing Vdef increases Y $.$

Y depends only on Vdef so changing Vacc has no effect on Y$.$

Y depends only on Vacc so changing Vdef has no effect on Y$.$

Increasing Vacc increases Y$,$ while increasing Vdef decreases Y $.$

Look at the formula for the deflection Y$.$ How does changing Vdef and$/$or Vacc affect Y$?$

Slope of the Graph

If we were now to measure the deflection Y for various combinations of Vacc and Vdef, and plot a graph

Y vs V$\_\{$def$\}\}/\{$V$\_\{$acc$\}\}$

what would we expect for the slope of the straight line generated? Don't forget to think about the units!
