AI Thread Summary
To stabilize the leaves of an electroscope, consider using larger pieces of aluminum foil, as smaller leaves may struggle to maintain control under high charge. Attaching a small weight to the wire can help prevent excessive flaring of the leaves. Additionally, using a stiffer wire or adding a piece of cardboard can enhance stability. A stronger adhesive for attaching the leaves to the wire may also improve their performance. Experimenting with different configurations will help achieve a balance between stability and responsiveness.

Hello,

I'm currently building an electroscope for a physics lab, and it's basically set up to be inside a glass jar, with two pieces of aluminum foil attached to a wire inside. The two pieces of foil move when charged objects come near, and it works well most of the time.

However, when there's a lot of charge brought near the electroscope, the leaves tend to flare out in several directions and sort of twist as well. I've tried making a small loop with the wire to control movement, but the same problem still occurs.

Does anyone have any suggestions on how I could modify the wire or even the leaves to solve this problem?

You might consider using larger pieces of foil for your leaves. Smaller leaves will be hard to control under a large charge. Of course, with the leaves being more massive, you will get a decreased separation with the same charge. You could also use one longer piece of foil folded in half. You should experiment with different sizes and setups until you find an acceptable compromise.
 


Hello, thank you for your question. It sounds like you are experiencing some issues with stabilizing the leaves of your electroscope. One solution you could try is attaching a small weight to the bottom of the wire, which can help keep the leaves in place and prevent them from flaring out too much. Additionally, you could try using a stiffer wire or attaching a small piece of cardboard or paper to the wire to add some stability. Another option would be to use a stronger adhesive to attach the leaves to the wire, ensuring they stay in place even with a lot of charge. I hope these suggestions help and good luck with your physics lab!
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
