The charge will get dispersed on the metallic sheet at the mouth of the jar and hence we need to give more charge on the knob of the electroscope to observe a deviation in the gold-leaves.
Explanation:
- Electroscope is a device used to detect any sort of charge with an idea of the charge intensity that is represented by the degree of deviation in the gold-leaf.
- Gold leaf is connected to the knob via a conducting material and this whole setup is insulated electrically and isolated form the atmospheric air by enclosing it in a glass.
- The top surface of the glass jar can be closed by the use of a cork or a cardboard so that suspended particles do not enter and hinder with the gold leaf inside the jar.
- When this is replaced by a metallic plate then any charge brought in contact to the knob will get conducted and will distribute uniformly over the plate.
