Electric flux through the square

AI Thread Summary
The discussion revolves around calculating the electric flux through a square when a point charge of +6μC is positioned 20 cm above its center. It is noted that the charge is not completely enclosed by the square, prompting the suggestion to use five additional squares to form a cube for proper enclosure. The concept of visualizing the problem in three dimensions is emphasized to understand the flux calculation better. The interaction highlights the importance of enclosing the charge to apply Gauss's law effectively. Overall, the solution requires a 3D approach to accurately determine the electric flux.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
