Electrostatic Induction
Physics ⇒ Electricity and Magnetism
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?
