What happens when a neutral glass rod touches a positively charged metal sphere?

In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod. 3. A neutral metal sphere is touched by a positively charged metal rod. In this case, electrons are transferred from the neutral object to the positively charged rod and the sphere becomes charged positively.

Why is the sphere on the left becomes negatively charged when a positively charged glass rod is brought near to it?

(b) A positively charged glass rod is brought near the sphere on the left, attracting negative charge and leaving the other sphere positively charged. In this case, electrons are attracted to the sphere through a wire called the ground wire, because it supplies a conducting path to the ground.

Why the positively charged rod causes the piece of foil to move?

The foil is moving because the foil and the conducting rod next to it are both negatively charged. As the rubber rod is brought near, electrons are pushed down into the electroscope, negatively charging the conducting rod and foil, leaving the top part positively charged.

When positively charged metal object is brought close and touches a neutral metal object?

If a positively charged body is brought near to a neutral or uncharged body, it induces a negative charge on the near side and a positive charge on the far side of the neutral object. This creates a force of attraction between the two bodies.

What happens when you bring a negatively charged rod near a piece of metal?

When two negatively charged objects are brought near each other, a repulsive force is produced. Excess electrons flow from the rod into the ball, and then downwards making both leaves negatively charged. Since both leaves are negatively charged, they repel each other.

When positively charged sphere is brought?

4. A positively charged balloon is brought near a neutral conducting sphere as shown below. While the balloon is near, the sphere is touched (grounded). At this point, there is a movement of electrons….

Is glass rod positive or negative?

A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged.

When glass rod is rubbed with silk glass rod acquires positive charge give reason?

One of the methods to charge material is by friction. That is why when we rub a silk cloth on a glass rod, there is a transfer of electrons from the glass rod to the silk cloth. As a result, the glass rod becomes positively charged and the silk cloth becomes negatively charged.
