Concept

Problem: The figure shows four electrical charges located at the corners of a rectangle. Like charges, you will recall, repel each other while opposite charges attract. Charge B exerts a repulsive force (directly away from B) on charge A of 3.6 N . Charge C exerts an attractive force (directly toward C) on charge A of 7.2 N . Finally, charge D exerts an attractive force of 2.4 N on charge A.Assuming that forces are vectors, what is the magnitude of the net force net exerted on charge A?What is the direction of the net force net exerted on charge A?

Problem Details

The figureA figure shows four charged particles labelled from A to D in the corners of a rectangle. Charges A and B are positive, charges C and D are negative. Sides AB and CD have the length of 141 centimeters. Sides AC and BC have the length of 100 centimeters. shows four electrical charges located at the corners of a rectangle. Like charges, you will recall, repel each other while opposite charges attract. Charge B exerts a repulsive force (directly away from B) on charge A of 3.6 N . Charge C exerts an attractive force (directly toward C) on charge A of 7.2 N . Finally, charge D exerts an attractive force of 2.4 N on charge A.
