Practice questions
In electrostatic induction, a charged body is brought near a conductor without touching it. Why does the charge distribution in the conductor change?When a positively charged rod is brought near a neutral conductor, what happens to the end of the conductor closest to the rod?When a negatively charged rod is brought near a neutral conductor, what happens to the end of the conductor closest to the rod?A neutral conductor is placed near a positively charged rod and connected to Earth. In which direction can electrons move through the connecting path?A neutral conductor is placed near a negatively charged rod and connected to Earth. In which direction can electrons move through the connecting path?If a conductor is connected to Earth, where can extra electrons go?When a charged rod is brought near a conductor without touching it, what is separation of charges inside it called?When a positive rod is brought near a neutral conductor, what effect appears at the near end?When a negative rod is brought near a neutral conductor, what effect appears at the near end?A positively charged rod is brought near a neutral conductor but not touched. What is the total charge of the conductor?A neutral conductor is kept near a positively charged rod, connected to Earth, and then the Earth connection is removed. What charge generally remains on the conductor?A neutral conductor near a negatively charged rod is earthed, and then the Earth connection is removed. What charge remains on the conductor?A conductor has zero total charge, but one end appears positive and the other negative. What can cause this situation?Why can a charged conductor become neutral when connected to Earth?A positively charged rod is brought near a neutral conductor, and the conductor is connected to earth. After removing the earth connection first and then removing the rod, what remains on the conductor?A positive rod is brought near a neutral conductor, and the conductor is earthed. After the earth connection is removed, the rod is removed. What is the final charge on the conductor?A negative rod is brought near a neutral conductor, and the conductor is earthed. After the earth connection is removed, the rod is removed. What is the final charge on the conductor?In charging by induction, why can final charging fail if the charged rod is removed before the earth connection is removed?A positive rod is brought near a neutral conductor. What effects appear at the near and far ends, respectively?A negative rod is brought near a neutral conductor. What effects appear at the near and far ends respectively?
