A charged object has two forces acting on it: F1 (4 Newtons, pointing up at 120 degrees from the positive x axis), and F2 (8 Newtons, pointing down -30 degrees from the positive x-axis).
(a) Write down F1and F2 in terms of the unit vectors i (along x-axis) and j (along the y-axis).
(b) Compute the total (net) force acting on the object and write it down in terms of i and j.
(c) Write down the total force in polar form, i.e. give its magnitude (in Newtons) and its orientation (angle from the positive x-axis)
