Two infinitely long straight current carrying wires are placed parallel to y-axis in xy plane. Each wire carries current I in opposite directions as shown. A charged particle of charge +q and mass m is project from position P(0,0,0a) with initial velocity v=i. Then

Answer»

The magnitude of initial ACCELERATION of the particle `(mu_(0)lqv)/(2piam)`
The DIRECTION of initial acceleration of the particle is PARALLEL to positve x-axis
The direction of initial acceleration of the particle is parallel to positive y-axis
The radius of curvature of the path of the particle just after it is projected is `(2pimav)/(mu_(0)lq)`
