A change q=1 C is at (3m,4m) and moving towards positive x-axis with constant velocity of 4 `m//s`. A long current carrying wire is at origin. Current in this wire is 2.A and towards positive z-axis. Magnetic force on the charge at given instant is

`(1.64xx10^(7)hatK)N`

`-(1.92xx10^(-7)hatK)N`

`(4.8hatJ-3.2hatK)xx10^(-7)N`

`(1.6hatJ-4.8hatK)xx10^(-7)N`
