consider an object with a charge of +7.0 C placed at the origin and an object with a charge of -3.0 C placed along the x-axis, 25 cm from the origin, at (25 cm, 0) and an object with a charge of +4.5 C placed on the y-axis at (0 cm, 15, cm). What is the electric field (magnitude and direction) at a point located at (25 cm, 15 cm). What is the electric potential at that same point If you put an object with a charge of -5.0 C at the point (25 cm, 15 cm), find the force on that object (magnitude and direction). If you put an object with a charge of -5.0 C at the point (25 cm, 15 cm), what is the total electric potential energy of the four objects
