A potassium ion K+ has mass 6.492 10-26 kg and is initially at rest on a Cartesian coordinate system at (-2.00 cm, 0). A sulfate ion SO4 2- has mass 1.595 x 10-25 kg and is placed at rest at (3.00 cm, 2.00 cm). Find the force on the sulfate ion and its acceleration. Give the directions of the vectors as standard position angles, measured counterclockwise from the positive x-axis
