Electrostatic Induction 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 Induction.
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 11
A metal sphere is initially neutral. A negatively charged rod is brought near it, and the sphere is then grounded. What is the sign of the charge left on the sphere after the ground and rod are removed?
A metal sphere is suspended by an insulating thread. A positively charged rod is brought near it, and the sphere is momentarily grounded. What is the net charge on the sphere after the ground and rod are removed?
A metal sphere of radius 5 cm is placed near a point charge of +10 μC. If the sphere is grounded while the charge is nearby, what is the sign of the charge induced on the sphere?
A neutral metal sphere is placed near a charged rod. If the sphere is grounded and then the ground is removed before the rod, what is the net charge on the sphere?
