Basically what does the second sentence of the mark scheme mean?- they will be attracted back if the cathode is positive- well the cathode is always negative right?
electrons are negative so they are attracted to the positive terminal (Anode).

yeah but the mark scheme says
electrons should be repelled by cathode and/or attracted by anode or they will be attracted back to the cathode/slowed down if cathode positive

but what im saying is the cathode cannot be positive
