each sketch below shows three objects with an electric charge. in each case, decide whether there is a net force acting on the object outlined in green. if there is a net force, decide whether it pushes the green - ring object to the left or right. then select the appropriate button under the sketch.\nfor example, if there is a net force pushing the green - ring object in the first sketch to the left, select the left button under the first sketch. if there is no net force on the green - ring object in the second sketch, select the middle button under the second sketch. and so on.

Answer

Explanation:

Step1: Recall Coulomb's law

Coulomb's law states that like - charges repel and opposite - charges attract.

Step2: Analyze the first sketch

The green - ring object is between a negative charge (-2) on the left and a positive charge (+2) and a negative charge (-1) on the right. The force due to the - 2 charge on the left is attractive (towards left), the force due to the +2 charge on the right is attractive (towards right), and the force due to the - 1 charge on the right is repulsive (towards left). The net force is to the left.

Step3: Analyze the second sketch

The green - ring object is between a negative charge (-1) on the left and a positive charge (+1) and a negative charge (-2) on the right. The force due to the - 1 charge on the left is attractive (towards left), the force due to the +1 charge on the right is attractive (towards right), and the force due to the - 2 charge on the right is repulsive (towards left). The net force is to the left.

Step4: Analyze the third sketch

The green - ring object is between two negative charges (-3) on the left and a negative charge (-3) on the right. All forces are repulsive. The two negative charges on the left push it to the right, and the negative charge on the right pushes it to the left. Since the two negative charges on the left are closer, the net force is to the right.

Answer:

Left for the first sketch, Left for the second sketch, Right for the third sketch.
