Electrostatic Shielding starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Electrostatic Shielding.
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 12
A conducting shell is grounded and placed in an external electric field. What is the potential inside the shell?
A hollow metallic sphere is given a charge and then placed in an external electric field. What happens to the field inside the sphere?
