Question about electric field of a point figure in book

AI Thread Summary
The discussion centers on understanding a figure from "Physics for Scientists and Engineers" by Giancoli, specifically regarding the electric field of point charges. It clarifies that the electric field of a negative charge points inward, while that of a positive charge points outward. Participants inquire about the significance of the force depicted in the diagram, particularly its direction relative to the electric field. The conversation also touches on relevant equations that describe the force experienced by a charge in an electric field. Overall, the focus is on clarifying concepts related to electric fields and forces in the context of the figure.

I'm studying for my physics exam and there is a figure on the book physics for scientists and engineers 4th edition by giancoli that i just don't understand. I know that the electric field of a negative charge points toward it and the electric field of a positive charge points away from it

Also why is the force included in that diagram, what does it mean if it is parallel to the electric field or points against it?

What is it you don't understand about the figure? What is included in parts (b) and (c) that does not appear in part (a)?

What relevant equation tells you the force that a charge experiences when subjected to an electric field?

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...
