if two charges +q and -q are kept at a certain distance. then wat will be the electric field at the point which is at a distance a frm the +q charge? answer in terms of variables... actually i have a conceptual doubt which can be cleared by the help of this ques...
|
Keep working....................Iam comming..
your's only,
Success!! |

the distance between the charges should be given. There is no gauss law application in this.

There is no better feeling in this world than being a winner! |

U can use gauss law here only to derive the field expression for sphere!!
well..electric field is a vector...directed towards a negative charge and away frm a +ve charge...
so according to the position of the point u can find the field...

You can treat the system as a dipole system,. The derivation for electric field due to a dipole can be found in any standard text. But you still need the distance between the two charges to define the dipole moment.
