If a particle of charge `10^(-12)` coulomb moving along the`hat(x)`-direction with a velocity `10^(5)m//s` experiences a force of `10^(-10)` newton in `hat(y)`-direction due to magnetic field. Then the minimum magnetic field is
A. `6.25xx10^(3)` tesla in `hatz`- direction
B. `10^(-15)` tesla in `hatz`- direction
C. `6.25xx10^(-3)` tesla in `hatz`- direction
D. `10^(-3)` tesla in `hatz`- direction
