Potential is same across the wire. so i get 4 pairs of parallel connections http://tinypic.com/r/2s9briu/7 How will I solve this?

Ok ! so what do I do? I can't find any points having same potential. how will i simplify the circuit?

Homework Statement The diagram represents a regular hexagon. The resistances are r each Find the effective resistance across points A & B http://tinypic.com/r/153n39d/7 Homework Equations The Attempt at a Solution A resistance less wire passes through one of the diagonals...

I haven't yet learned Taylor expansion. So is there any other method ? I actually found this question in a magazine. The answer page was torn. So i don't know the answer too. I have tried solving it 8-10 times but with no success ! (cant reach the final expansion) I found this sum interesting...

But what about the electrstatic force. It constantly changes as the distance between the charges change. how to incorporate that. I know by intergrating the force, but then what to do?

1. Homework Statement Two Springs are present (one just infront of the other). The Spring towards the left has +Q charge and towards the right -Q charge (at their ends).The distance between the two charges is d. The Springs are of length l. Find the Time Period of the Simple Harmonic Motion...

Ok.. so is this the way ? M (√3/2)v R1 (1/2) = M (v/2) R2 therefore , R2 = (√3/2)R1 (so what is the use of energy conservation?) and I was thinking about the path of +2q charge. It would be repelled by the +Q charge, so it shouldn't move towards the +Q charge. So how will the path of +2q...

Homework Statement A charge +Q is fixed. Another charge +2q and mass M is projected from a distance R from the fixed charge at and angle 30 with the horizontal towards the fixed charge (like a projectile) at a speed of v Find the minimum separation between the two charges if the velocity...
