I don't know if its just me, but I think the wording of the question is weird and I'm not really understanding what it is saying. I have stared at this problem for many hours and have even went to the teacher to try to clarify. The teacher provide us with the actual work on how to calculate...
Er i don't know much about it. The shape was kinda like a gun where at the tip, it can measure magnetic fields in two ways. It can be by axial and i forgot what the other one was called. When we measured it it was about 4 cm away from the magnet. We did the same distance for both poles but...
In lab, we used a bar magnet and a device that can measure magnetic fields. We put the measuring device near the north part of the pole and it measured 9T. We did the same to the south, but it gave us 75T. I was expecting it to give somewhere around -9T, is that what is suppose to happen? We...
Oh, ok. Just to make sure,
to sum it up, that repelling force that i saw was because the electrons from the paper clip is being transferred to the van de graf. Then that electron is removed from the van de graf and eventually, there will be more proton repelsion than electron/proton...
Hi, I'm still confused on how a Van de Graaf generator works
We did a lab involving it and my observation is as listed:
Rubber band: the rubber band would stick for a short while, but then would bounce off momentarily, and would repeat this process.
Paper clip with string: The...
Have you learned to calculate force normal yet? We can calculate the force normal by knowing the weight(mass and gravity) and the angle of the ramp(assuming it is a ramp). Force normal is the force applied perpendicular to the surface. So there must be a force applied to cancel out the force...
My semester just started and I'm already struggling.
The diagram is a square with a dot on each corner representing a charged particle. 1 at top left, 2 at top right, 3 at bottom left, and 4 at bottom right. The distance on one side of the square is a
The problem reads In fig. 21-22, four...
