Question

One coulomb of point charge moving with a uniform velocity 10x^10 \hat{x} m/s enters the region x≥0x \geq 0 having a magnetic flux density B⃗=(10yx^+10xy^+10z^)\vec{B} = (10y \hat{x} + 10x \hat{y} + 10\hat{z}) T. The magnitude of force on the charge at x=0+x = 0^+ is ______ N.
(x^\hat{x}, y^\hat{y}, and z^\hat{z} are unit vectors along x-axis, y-axis, and z-axis, respectively.)
