Two charged particles are positioned in the xy plane. Q$1=5\mathrm{.}08$ nC charge is located at $(0\mathrm{.}00,4\mathrm{.}2)$ m$,$ Q$2=-4\mathrm{.}4$ nC charge is located at $(0\mathrm{.}00,0\mathrm{.}00)$ m$.$

A$)$ What is the vector electric field at point P located at $(2\mathrm{.}09,1\mathrm{.}61)?$

B$)$ what is the vector force on a $+2\mathrm{.}96$ C test charge placed at point P $(2\mathrm{.}09,1\mathrm{.}61)?$

C$)$ what is the magnitude of the force in b$?$

Submit answer C in units of N rounded to $2$ decimal places
