A particle of charge `q` is projected from point `P` with velocity `v` as shown. Choose the correct statement from the following.

Options

A. Magnetic field at `P` is `(mu_(0)i)/(4pir)[2+sqrt(2)]odot`
B. The magnetic field at `P` is `mu_(0)i//2pir.`
C. The particle initially accelerated towards wire `A`.
D. The particle initially accelerated towards wire `B`.

Explanation

Magnetic field at `p` is into the plane `(ox)`. Initially `vecF=qvecvxxvecB` is towards the wire `A`.
