State and explain how the deflection of the $\alpha$-particles changes when the magnitude of $V$ is increased.
State and explain how the deflection of the $\alpha$-particles is affected when the plate separation $d$ is reduced.
The source of $\alpha$-particles is replaced with a source of $\beta$-particles. Compare, with a reason for each, the effect of the charge of $\alpha$- and $\beta$-particles on their deflections in a uniform electric field.
The source of $\alpha$-particles is replaced with a source of $\beta$-particles. Compare, with a reason for each, the effect of the mass of $\alpha$- and $\beta$-particles on their deflections in a uniform electric field.
The source of $\alpha$-particles is replaced with a source of $\beta$-particles. Compare, with a reason for each, the effect of the speed of $\alpha$- and $\beta$-particles on their deflections in a uniform electric field.
The electric field produces an acceleration of the $\alpha$-particles and the $\beta$-particles. Determine the ratio \[ \frac{\text{acceleration of the } \alpha \text{-particles}}{\text{acceleration of the } \beta \text{-particles}}. \]
