$($I$)$ The electric field at a point in pace is given by vec$(E)=(-400$hat$(i)+100$hat$(j))\frac{N}{C}.$

A$.$ What is the electric force on a positive $1\mathrm{.}0$nC charge at this point? Give your answer in

component form.

B$.$ What is the electric force on a negative $1\mathrm{.}0$nC charge at this point? Give your answer in

component form.

C$.$ What are the magnitudes of the acceleration felt by both charges from $(A)$ and $(B)$ in this

field?
