Can you Give an example? I'll look for total EM force part Thanks.

Two charges are moving mutually perpendicular to each other in space with constant velocities. The moment one charge crosses over the line of path of second charge the force on 1st charge (located just behind the 2nd charge moving away from it) appear to be zero (Magnetic field due to 2nd...

E near a charged ball will represent ELectric Field Intensity which is not Energy. So it can't be equated in energy. E or V are just two different visualisations of behavior of space around a charge (Region is called Electric Field). Energy here will be electric potential energy as scottdave...

I guess this will help.

It's a static problem so the net force is zero and the net torque about any point is zero. I agree with static problem thing. But how can we get F1 and F2.

Infinity in case of potential is arbitrary (V=0). So i guess Workdone in bringing to P and B might be different. E= -(dV/dr) so potential will drop differently in both directions, making V=0 at different 'infinities'. (Note: Don't take infinity literally). Correct me if I'm wrong.

Work done : W(Infinity to P)+W(P to Q) = W(infinity to B) + W(B to A) I don't see any contradiction.
