Question

During induction, a positively charged rod is brought near to but not touching the electroscope. The presence of the charged object above the plate of the electroscope induces charges to move down into the gold leaves, giving the electroscope an overall positive charge. The positive leaves repel. The same process occurs when a negative rod is brought close to the electroscope. This time, the negative charges flow through the electroscope to the leaves. The leaves, once again, repel. Whether the charge is positive or negative, in each case, the experiment shows that

Answer 1

this is the law of conservation of charge, this means that it is easily observed in the induction charging process.
