Expert Answer
a) Both A and R are true, and R is the correct explanation of A.
As we know, cathode rays are streams of electrons, which are negatively charged particles.
As we know, cathode rays are streams of electrons, which are negatively charged particles.
When cathode rays are placed in an electric field, they are deflected towards the positive plate, due to the force of the electric field on the negatively charged particles.
This is consistent with the behavior of charged particles in an electric field, and so R is a correct explanation of A.
