(b) Gold leaves fold back when touched with hands because the charged is ‘earthed’.

Hence, When the disc of GLE is touched with positively charged glass rod the charge on the leaves of GLE is positive.

The GLE apparatus has a disk that conducts charge while it has gold leaves that move to show the nature of charge. For example, If we bring the charged body near its disc, the leaves further diverge, then body is negatively charged. However, if leaves collapse, charge G.L.E positively.

A light gold leaf G is attached to the lower end of the rod. If the electroscope is positively charged by touching the plate with a positively charged glass rod, G will be repelled from R, because both now carry a positive charge.

Answer: Nothing will happen. The gold leaves will remain as they were.

When the metal terminal is touched with a charged object, the gold leaves spread apart in an inverted ‘V’. This is because some of the charge from the object is conducted through the terminal and metal rod to the leaves. Since the leaves receive the same sign charge they repel each other and thus diverge.

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.

When a negatively charged object is brought near a positively charged object, an attractive force is produced. Since both leaves are negatively charged, they repel each other. When the rod is removed, the electroscope will remain charged because of the extra electrons added to it.

• Gold leaves of an electroscope has positive charge hence they are diverged.
• The gold leaves of a gold-leaf electroscope are enclosed in a glass bottle.
• You are provided with a negatively charged gold leaf electroscope.
• Describe how we can use gold leaf electroscope to detect the nature of charges on a charged object.

The rod or strip still acquires a net negative charge by removing some electrons from the fabric or wool. While touching the ball of the electroscope with one hand, position the charged rod near (but not touching) with the other. The positive charge in the leaves is then neutralized, and the leaves collapse.

Yes, when the charge on one body (q1) is much greater than that on the other (q2) and they are close enough to each other so that force of attraction between q1 and induced charge on the other exceeds the force of repulsion between q1andq2.

When an atom or group of atoms has more electrons than protons, it is negatively charged. When an atom or group of atoms has more protons than electrons, it is positively charged.

Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.

When you bring a negatively charged object close to a neutral pith ball, These positive and negative charges attract the two closer and if they touch each other, positive charges get nullified and both bodies become negatively charged. Once both are negatively charged, they tend to repel each other.

When two neutral objects come into contact–especially in a dry environment–electrons can be knocked loose from one object and picked up by the other. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged.
