A negatively charged rod is brought near an electroscope without touching it. The leaves are initially separated, and as the rod is brought closer, the leaves move further apart. What is the charge on the electroscope?
Homework Answers
Since the negatively charged rod does not touches the microscope , the net charge on the microscope is zero.
Explanation:
as the negatively charged rob brought very close to the microscope then the free electron in the microscope knob repelled by the rod enter through into the leaves through stem.
as the two leaves have the same excess of negative charge so that they repell each other.
the know becomes postive charge
the net charge on the microscope = the excees charge on the knob + the excess chargeon the leaves = 0

An electroscope is charged by touching it with a negatively charged rod. The electroscope leaves spread apart and the rod is removed. Then another, negatively charged rod is brought near the top of the electroscope without touching. What happens? A. You are unable to make the observation because the rod is attracted to the top of the electroscope causing them to touch after all. B. The leaves do not change their position. C. The leaves move closer together. D. The...

Ground your electroscope. Touch a negatively charged rod to the metal plate of the electroscope. Draw in the schematic how the charges are distributed, and indicate the new deflection of the rotating pointer once it has come to equilibrium + Perform this experiment with the charge remaining from step 3. Recharge your negatively charged object and bring it into close proximity to the metal plate without touching. We are charging by induction in this case. How does the...

4. A negatively charged rod is brought near a metal sphere supported by an insulating stand point) without touching it. What happens to the free electrons in the sphere? OThey pass from the sphere into the stand. OThey are pushed out of the sphere and into the air OThey are pulled out of the sphere and into the rod. OThey shift away from the rod on the sphere.

After charging the plastic rod negatively by rubbing with the fur, bring it near to (but not touching) the proof plane and keep it there for a second. Then, while keeping the plastic rod near (but not touching) the proof plane, move the proof plane away from the grounded object. Once contact between the proof plane and the bar is broken, the rod is moved away. How does the proof plane acquire charge without touching the charged rod?
