Electric Field Direction: Help Determine from Experiments

AI Thread Summary
The discussion revolves around determining the direction of the electric field in an experiment involving a glass pan with copper and lead electrodes. Measurements indicated that voltage increased from the lead to the copper, suggesting the electric field direction is from the positive lead towards the copper. The principle that the electric field direction aligns with the force on a positive test charge is emphasized. Understanding the relationship between electric field (E) and force (F) is crucial for this determination. The conclusion is that the electric field points from the positive lead to the copper.

Homework Statement


We had an experiment in class where we had a glass pan with a piece of copper and lead with positive and negative leads attached. I have to figure out in which direction the electric field goes. We measured the voltage an numerous places in the pan. The numbers go bigger as they went form the lead to the copper. Can someone assist me in determining the direction of the electric field?

If you have a positive charged body and place a positive test charge near the body, the electric field will be in the direction of the force on the test charge. i.e. E=F/q where E and F are vectors.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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 'Rolling without slipping on a curved surface'

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 .
