Both the leaves of the electroscope carrya)Same chargesb)zero chargec)...
When the metal terminal is touched with a charged object, the gold leaves spread apart in a 'V'. This is because some of the charge on the object is conducted through the terminal and metal rod to the leaves. Since they receive the same sign charge they repel each other and thus diverge.

Both the leaves of the electroscope carrya)Same chargesb)zero chargec)...
Explanation:
An electroscope is an instrument used to detect the presence and magnitude of electric charges. It consists of a metal rod with two thin metal leaves attached to the bottom end. When a charged object is brought close to the electroscope, the electric charge induces a separation of the charges in the metal leaves, causing them to repel each other and stand apart.
Charge on the leaves:
The leaves of the electroscope carry the same charge. When a charged object is brought close to the electroscope, the charges in the object induce a separation of charges in the electroscope. The charges on the metal rod are redistributed among the metal leaves such that they carry the same charge.
Reason for same charge:
The metal rod of the electroscope is a conductor, and the charges in the object induce a redistribution of charges in the conductor. The charges on the metal rod are free to move, and they distribute themselves in a way that minimizes the electric potential energy of the system. This redistribution of charges results in the metal leaves carrying the same charge.
Conclusion:
Therefore, we can conclude that the leaves of the electroscope carry the same charge when a charged object is brought close to it.

When u touch the knob of the electroscope with a negatively charged object, the electrons will flow into both leaves.. So, both of them carry charge of same sign and they repel, and the extend of repulsion can be used to measure the amount of charge in the body
