24. Electric Force & Field; Gauss' Law

Determine the magnitude of the acceleration experienced by an electron in an electric field of 756 N/C. How does the direction of the acceleration depend on the direction of the field at that point?

A $-12\text{nC}$ charge is located at $(x,y)=(1.0\text{cm},0\text{cm})$. What are the electric fields at the positions $(x,y)=(5.0\text{cm},0\text{cm}),(-5.0\text{cm},0\text{cm)}$, and $(0\text{cm},5.0\text{cm})$? Write each electric field vector in component form.
