Problem

A point charge

q_1 = +4\,\mu\text{C}

is placed at the origin. A second charge

q_2 = -2\,\mu\text{C}

is located at the point

(0.30\,\text{m},\;0.40\,\text{m})

in the

xy

-plane. Calculate the electrostatic force (magnitude and direction) acting on

q_2

and express your answer in the form

F_x\,\hat{\mathbf i}+F_y\,\hat{\mathbf j}

(in newtons).
