I just confused about it.Why can't we discribe a particle just one wave function instead of wave packet(group of waves with different phase velocities)?
yes they are same
because of charges will create magnetic field as i derived formula and they will have much mass when they are moving as fast as near light's speed
coulumb's force says that same charge push themselves and if you looking at the charge when you the same speed you must see they...
Can someone explain? When two charge moving as fast as possible , what force is acting on for blocking to collide.I mean if you think you are not moving and you are looking 2 charge which are moving as fast as to near light speed, they must collide each other if charge is not increasing...
