Is it possible?



Easy, yet Interesting!

Given are 2 positively charged infinite rods of a finite charge density k.

The rods, both move parallel to their length with a speed 'v' in the same direction. Find 'v', if they are to remain in equilibrium.


Bonus question:- A particle of charge q and instantaneous position r, is moving with a velocity v. Find the magnetic field vector at a point with position vector r1.

    yeah, speed of light... dont kno if its possible though, coz a lot of things cum into action ven u start talking about moving at light speed
    @bonus: mu*q[Vx(r1-r)]/4pie|r1-r|^3 ?
    here x denotes cross product

    can this be done with only electrostatics knowledge
    as i am unable to solve this question
    and please also post the solution os electostat question (two spheres wala)

    no, electrostats is not enough for this

    and the solution to that had been provided long time back, check the post itself
