Apoint charge q₁= -6 x 10⁻³c and is at (5m, -4m). a point charge q₂= +2 x 10⁻³c is at (5m, 2m). both of these charges are "stuck" and will not move. a. find the electric field at point p(-2m, -3m). write in component form. *make sure you draw vectors and their components. b. find the electric potential at point p. c. a third charge q₃= -4 x 10⁻³ moves to point from very far away. what is the work done by the electric field on q₃.
