A positive object touches a neutral electroscope, and the leaves separate. Then a negative object is brought near the electroscope but does not touch it. What happens to the leaves?*1 pointThey move closer togetherThey move further apartThey remain in the same positionThey detach from the electroscop

The metal knob of a gold leaf electroscope is touched with a positively charged rod. When it is taken away the leaves stay separated. Now the metal knob is touched by negatively charged rod. The separation between the leavesincreasesdecreasesremains samefirst increases then decreases.

The positive charge flows from the electroscope to the groundThe negative charge flows from the electroscope to the groundThe negative charge flows from the ground to the electroscopeThe electroscope stays neutral because the rod doesn’t touch it

The arm of a neutral electroscope is vertical, as shown in Figure 1. The electroscope is given a charge, and the arm moves to the position shown in Figure 2. Then a uniformly charged non-conducting rod is brought near the top of the electroscope, and the arm of the electroscope moves to the position shown in Figure 3. Which of the following must be true about the charge on the electroscope and the rod?

A negatively charged rod is brought near an uncharged, grounded electroscope. Which of the following statements is true?

A positively charged rod is brought near the disc of a positively charged gold leafelectroscope. State your observation with reason
