2019 P1 Q2 - Deflection of Charged Particle in Electric Field
Here's 2019 A Levels H2 Chemistry Paper 1 Question 2:
This question is really straightforward so we can get the answer quickly.
1. Direction of Deflection in Electric Field
Electrons, which are negatively charged, will be deflected towards the positive electrode or (+) plate.
Protons, which are positively charged, will be deflected towards the negative electrode or (-) plate.
So we can eliminate options A and B.
2. Extent of Deflection
The angle of deflection of charged particle in an electric field is directly proportionate to the charge / mass ratio.
The greater the charge and smaller the mass, the greater the extent of deflection.
The charge of both an electron and proton have the same magnitude of 1 unit.
Since electrons have a much smaller mass as compared to protons, electrons will be deflected more.
Hence the answer to this question will be option C.
