AI Thread Summary
To identify positive and negative charges using vector components, remember that opposite charges attract while similar charges repel. The electric field from a positive charge points away, whereas from a negative charge, it points toward the charge. Analyzing the vector components can simplify the process by allowing you to focus on the direction of the forces. It's important to clarify specific examples if confusion arises. Understanding these principles will aid in accurately determining charge types.

How would I know when the charges are negitive and positive? Along the x and y-axis Thanks in advance for your help.

You'll need to be more specific. Do you have an example that confuses you?

Some tips that might help: Opposite charges attract; similar charges repel. The field from a positive charge points away from the charge; The field from a negative charge points toward the charge.
 
And with that you take the components of the vectors, in that way, you eliminate for the moment the vectorial behaviour and work directly on the components (taking the direction like + or -).
 

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 .

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...
