Answer :
An electroscope is used to detect the presence of an electric charge. It consists of two metal plates or leaves that are suspended from an insulating support. When an electric charge is brought near the electroscope, the leaves will diverge due to the electrostatic force of repulsion between them.
The extent of the divergence will depend on the magnitude of the charge. However, it is not possible to determine the sign (positive or negative) of the charge from an electroscope alone.
An electroscope is a device used to detect the presence of an electric charge. To tell if an electroscope has an electric charge, you can observe the behavior of the metal leaves on the electroscope.
When an electroscope has an electric charge, the metal leaves on the electroscope will spread apart. This is because the same charge on the metal leaves repels each other, causing them to move away.
It is not possible to tell from an electroscope alone what kind of charge it has. To determine the type of charge, you will need to use another device to induce a charge on the electroscope and observe the behavior of the leaves. If the leaves move away from each other, the electroscope has a positive charge. If the leaves move towards each other, the electroscope has a negative charge.
