Electric Charge and Its Properties starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Electric Charge and Its Properties.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 8
A metal sphere is given a positive charge by touching it with a positively charged rod. What method of charging is this?
Describe the difference between a conductor and an insulator in terms of electric charge.
Describe what happens when two objects with unlike charges are brought close to each other.
Explain what is meant by the statement 'charge is conserved'.
A metal sphere is given a positive charge by touching it with a positively charged rod. What method of charging is this?
A neutral metal sphere is suspended by an insulating thread. A negatively charged rod is brought close to (but does not touch) the sphere. Describe and explain what happens to the distribution of charges on the sphere.
A plastic ruler is rubbed with a dry cloth and then brought near small pieces of paper. The paper pieces are attracted to the ruler. Explain why this happens, even though the paper is neutral.
Explain why a charged balloon can stick to a wall, even though the wall is electrically neutral.
