Electric Field Strength charges

AI Thread Summary
Charge B, with 20 electric field lines, and Charge C, with 30 lines coming in, will experience the largest force between them when placed one cm apart. The number of electric field lines is a relative measure of field strength, indicating that Charge C has a stronger influence due to its higher number of incoming lines. The relationship between the number of lines and charge magnitude suggests that Charge C is significantly stronger than Charge A, which has only 10 lines. Therefore, the interaction between B and C is expected to yield the greatest force. Understanding electric field lines is crucial for analyzing the forces between charged objects.

Homework Statement


Charge A has 10 electric field lines coming out, Charge B has 20 lines coming out, and Charge C has 30 lines coming in. Which pair of these charges will have the largest force between them if placed one cm apart?


Homework Equations





The Attempt at a Solution


Is it B and C just because they have the most amount of lines??

Yes. WHen drawing electric field lines, the number of lines are only a relative quantification of the field strength. If field lines are properly drawn, then 3 x the number of lines emanating from a charge indicates a charge 3 x as great.

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...
