The accelerating voltage is Vacc = 2 3 2 V The deflecting voltage is Vdef = 2
Fantastic news! We've Found the answer you've been seeking!
Question:
The accelerating voltage is Vacc V
The deflecting voltage is Vdef V
The length L of the deflecting plates is cm
The separation d between the deflecting plates is mm
The distance D from the deflecting plates to the screen is cm
vxE
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 andor 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 VdefVacc
what would we expect for the slope of the straight line generated? Don't forget to think about the units!
