equipotential Definition and 104 Threads

We haven't really covered this in class so I need some help. Assuming that these contours are those of a point charge at the origin, calculate the value of the charge in C. I tried using the equation kQ/R but that's wrong, I'm not even sure I'm using it right in fact. Any help? Thanks

Field Lines and Equipotential lines Why can't 2 field lines cross, and why can't 2 equipotential lines cross? I understand that equipotential lines are perpendicular to field lines. And I see that it'd be impossible to find an equipotential line if two field lines have crossed, since there...

This is the same equipotential lines thread that you may have read in the Linear and Abstract Algebra. I have questions… 1. Why don't birds sitting on power cables atop transmission posts get electrocuted? Why do boys get electrocuted when the thread of the kite they are flying...

Indeed, it's me again... asking some questions... 1. Why don't birds sitting on power cables atop transmission posts get electrocuted? Why do boys get electrocuted when the thread of the kite they are flying accidentally touches a power cable? 2. When you walk across a carpeted floor and...
