online doubt clearing?
A non conducting ring of radius 0.5m carries a total charge of 1.11*(10 pow -10)C distributed non uniformly on its circumference producing an electric field Every where in space. The value of line integral (integration from l=1/0 to l=0)- Edl (l=0 being center of the ring) in volt is
1. +2 2. -1 3. -2 4. 0 (please give complete explanation) |

ApoorvGoel, I'm having trouble understanding your limits of integration. Is the 1/0 a typo or is it some notation I'm not familiar with?
At any rate, the line integral of a static electric field will be equal to the potential difference from the beginning of the line to the end. Thus if you start and end at the same point, the answer will always be zero. If you start and end at different points, you can either compute the line integral directly or do like I said and find the difference in potential. |

1\0 means infinite
And Please give your final choice with proper explanation |

Aaah... 1/0. Got it. :)
So you just need to do as I said and compute the difference in potential from start (l=0) to finish (l= As for the potential at the center of the ring, I'll leave that up to you. We're here to HELP you with your homework, not do it for you. A simple Google search will reveal the formula, but it's not very hard to figure it out yourself. Just integrate kQ/r over the entire ring. |
