The electric field is expressed as:

$\overline{){\mathbf{E}}{\mathbf{=}}\frac{\mathbf{k}\mathbf{q}}{{\mathbf{r}}^{\mathbf{2}}}}$, where E is the electric field, k is Coulomb's constant, q is the charge, and r is the distance.

A.

The electric field, E = < 0, 5. 104, 0> N/C  is in the y-direction only.

This means that the electric field in the x-direction and z-direction is zero.

The charged particle will be placed only on the y-axis.
