a) Is it true or wrong to say that components in series must have the same potential difference across them? Either yes or no explain it. Marks = 5
b) Is it true or wrong to say that magnetic force vectors on charged particles point in the same direction as the magnetic field? Either yes or no explain it. Marks = 5
Both of these statements are incorrect.
Since it's a long answer question, you ought to give them a try based on what you know about potential drops and the nature of the magnetic force.
