Final answer:

Electron transfer occurs when substances are rubbed, gold-leaf electroscope tests charges, and a charged conductor creates electric field intensity.


Explanation:

When two suitable substances are rubbed against each other, electrons will be transferred from one substance to the other. This is known as triboelectric charging, where electron transfer causes one material to become positively charged and the other negatively charged. A gold-leaf electroscope is indeed used for testing charges, as it can detect the presence and type of charge on an object. Outside a charged plane conductor, there is an electric field intensity due to the presence of charges causing electric field lines to extend into the space surrounding the conductor.
