Electrostatics – One mark and two marks questions for practice

So far we were concentrating on 3 and five marks questions only. Now I think that concentrating on one and two marks questions will further increase the chance of scoring better.

It’s true that just by concentrating on the three marks and five marks questions one can easily score greater than 60% marks. But it is not enough. When you CAN SCORE MORE why should you compromise for less?

Often the one and two marks questions are tricky and twisted. But, when the questions are tricky, there is a greater chance to score. All you need is to apply your commonsense (often complained that it is not so common!) and logical reasoning. The basic facts remain the same however the question maker twist them. So, believe that whatever question asked are based on what you have learnt. But beware!, whatever conclusions you draw must satisfy your commonsense as well as that of the examiner.

So, here are a collection of one mark and two marks questions from ELECTROSTATICS. The straight – forward questions are intentionally avoided.
