How Does Gauss's Law Explain Net Flux in Electric Fields?

AI Thread Summary
The discussion focuses on applying Gauss's Law to determine the net flux through a closed surface surrounding two charges, q and -q. With 24 electric field lines emanating from the positive charge and 15 terminating at the negative charge, the net flux is analyzed. Since the charges are equal in magnitude and opposite in sign, the net flux through the closed surface is concluded to be zero. A conceptual approach involves counting the lines entering and exiting the surface to confirm this result. Ultimately, Gauss's Law effectively illustrates that the net flux for a dipole configuration is zero.

A figure showing electric field lines has two charges, q and -q. There are 24 lines emanating from the +q charge. 15 of these lines terminate at -q. There are 24 lines terminating at the q- charge. What is the net flux through the surface surrounding the two charges?

Well it is a dipole with the two charges being of equal magnitude, so wouldn't the net flux be 0?
 
It's a closed surface right? Then just apply Gauss law. A more "conceptual" approach is to count how many lines are entering the closed surface and how many are exiting. Then find the net number of lines exiting the surface.
 

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...
