Solve the all parts of given question:
Question: A charge 4.99nC is placed at the origin of an xy-coordinate system, and a charge -2.00nC is placed on the positive x-axis at x = 3.98cm. A third particle, of charge 5.97nC is now placed at the point x = 3.98 cm, y = 2.96cm.
Part I: Find the x-component of the total force exerted on the third charge by the other two.
Part II: Find the y-component of the total force exerted on the third charge by the other two.
Part III: Find the magnitude of the total force acting on the third charge.
Part IV: Find the direction of the total force acting on the third charge.
