What happens when a negatively charged rod touches a negative electroscope?

When the negatively-charged rod is brought close to the electroscope, positive charges are attracted to it and negative charges are repelled away from it. If they are brought into contact, they will both take a net negative charge.

What happens when an electroscope is negatively charged?

When a negatively charged electroscope is touched, electrons leave the electroscope to the ground. The excess electrons leave the electroscope, thus neutralizing its overall charge. As the electroscope loses its charge, the needle relaxes back to its naturally upright position.

What happens when a positively charged rod is brought near a negatively charged electroscope?

If a positively charged object is brought near a negatively charged electroscope, it will attract some of the excess electrons up the stem and out of the leaves, causing the leaves to come slightly together. That process causes both of the leaves to be positively charged and the leaves will diverge.

How would a negatively charged rod brought near to the cap affect the electroscope?

When a negatively charged body is brought near the cap of a gold leaf electroscope whose case is earthed,then the electrons near the brass disc of the electroscope gets repelled and so they move from the brass disc to the leaves .

What happens when you touch a negatively charged electroscope with your finger?

The leaves of an electroscope collapse as soon as we touch the metal cap with hand because the leaves of the charged electroscope lose charge to the earth through our body. This process is known as EARTHING.

What happens if you touch electroscope?

When the positively charged electroscope is touched, its charge becomes grounded (or neutralized). This is depicted in the animation below. The grounding process involves a transfer of electrons between the charged electroscope and the conducting object to which it is touched.

What happens when a positively charged rod touches an electroscope?

Similar to the results of a negatively charged rod, if a positively charged rod is brought near the knob of a neutral electroscope, it will attract some electrons up from the leaves onto the knob. That process causes both of the leaves to be positively charged (excess protons), and the leaves will diverge.

When a charged rod is brought near a negatively charged electroscope the leaves diverge more?

When a positive charged rod is brought near the disc of a negatively charged gold leaf electroscope, it is observed that the divergence of leaves decreases and the rod is positively charged because the electrons move from leaves to the disc with the result that negative charge on leaves decreases.

When a negatively charged rod is brought near the cap of a gold leaf electroscope?

Dear student, when a negatively charged body is brought near the cap of a (negatively charged) gold leaf electroscope, it repels the electrons in the cap. These electrons go to the gold leaves, and due to increased repulsion due to increased number of electrons, the leaves will be diverged.

What will be the charge on the leaves of an electroscope if you bring a negative rod near the end of its metal cap?

Hence, the charge on the metal cap is negative and the charge on the leaves of electroscope is positive.

When a negatively charge rod is brought near the cap of a gold leaf electroscope whose case is earthed then?

When a negatively charged rod is brought near the cap of a gold leaf electroscope whose case is earthed, then the leaf has an induced negative charge.

When a negatively charged rod is brought near the cap of a gold leaf electroscope whose case is 8 then?
