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 12
A conducting sphere of radius 10 cm is placed near a point charge of +5 μC. If the sphere is grounded, what is the sign of the induced charge on the side of the sphere closest to the point charge?
A metal sphere is charged by induction using a negatively charged rod. If the sphere is then touched by hand, what will be its final charge?
A metal sphere is charged by induction using a positively charged rod. After the process, what is the sign of the charge on the sphere?
A metal sphere is initially neutral. A negatively charged rod is brought near it, and the sphere is then grounded. What happens to the electrons in the sphere during grounding?
A metal sphere is suspended by an insulating thread. A negatively charged rod is brought near the sphere, and the sphere is momentarily grounded. What is the final charge on the sphere after the ground and rod are removed?
A neutral metal sphere is placed near a positively charged rod. If the sphere is then grounded, what will be the net charge on the sphere after the ground connection is removed and the rod is taken away?
Describe the difference between charging by conduction and charging by induction.
Describe the steps to charge a metal sphere negatively by induction using a negatively charged rod.
Describe what happens to the distribution of charges in a conductor when a charged object is brought near it but not touching.
Explain why a charged object can attract a neutral conductor by induction.
Explain why grounding is necessary in the process of charging by induction.
If a charged object is brought near a conductor and then removed without grounding, what is the net charge on the conductor?
If a positively charged rod is brought near a neutral conductor and the conductor is grounded, what type of charge will the conductor acquire after the ground and rod are removed?
What is electrostatic induction?
When a negatively charged rod is brought near an uncharged metal sphere, what type of charge is induced on the side of the sphere closest to the rod?
