Define electric field strength in words.
Calculate the time required for the electron to travel from A to B.
Calculate the size of the electric field strength.
Show that the electron’s acceleration in the field is $1.1 \times 10^{16}\,\text{m s}^{-2}$.
Use the acceleration from (iii) together with your answer to (i) to find the vertical distance $y$ between point B and the upper plate.
Explain why the calculation in (iv) does not need to include the gravitational effects on the electron.
At time $t = 0$, the electron enters the field. On Fig. 2.2, sketch graphs to show how, with time $t$, (1) the horizontal component $v_x$ of the electron’s velocity, and (2) the vertical component $v_y$ of the electron’s velocity vary. You do not need numerical values.
Use the acceleration from (iii) along with your answer to (i) to find the vertical distance $y$ from point B to the upper plate.
Explain why the electron’s gravitational effect can be omitted from the calculation in (iv).
At $t = 0$, the electron enters the field. On Fig. 2.2, sketch graphs to show how the horizontal component $v_x$ of the electron’s velocity and the vertical component $v_y$ of the electron’s velocity vary with time $t$. No numerical values are needed.
