Questions: Each sketch shows three objects with an electric charge. In each case, decide whether the net force on the object outlined in green is to the left, or to the right, or if there is no net force acting on the object outlined in green. There is a net force acting on the object outlined in green. For example, if there is a net force pushing the green object to the left, select the left arrow. If there is no net force on the green object in that sketch, select the middle button under the second sketch. Select the right arrow under the third sketch if there is a net force pushing the green object to the right.

Solution

Solution Steps

To solve this problem, we need to analyze the forces acting on the object outlined in green due to the other charged objects. The direction of the net force depends on the relative positions and magnitudes of the charges. Since the sketches are not provided, I will outline the general approach to determine the direction of the net force.

Step 1: Understand Coulomb's Law

Coulomb's Law states that the force between two point charges is given by: \[ F = k \frac{|q_1 q_2|}{r^2} \] where \( F \) is the magnitude of the force, \( k \) is Coulomb's constant, \( q_1 \) and \( q_2 \) are the magnitudes of the charges, and \( r \) is the distance between the charges. The force is attractive if the charges are of opposite signs and repulsive if they are of the same sign.

Step 2: Analyze Forces on the Green Object

For each sketch, identify the charges and their positions relative to the green object. Determine the direction of the force exerted by each charge on the green object:

If the charge is positive and the green object is also positive, the force is repulsive.
If the charge is negative and the green object is positive, the force is attractive.
The opposite applies if the green object is negative.

Step 3: Determine Net Force Direction

Sum the forces vectorially to determine the net force on the green object:

If the net force vector points to the left, the net force is to the left.
If the net force vector points to the right, the net force is to the right.
If the forces cancel each other out, there is no net force.

Final Answer

Since the specific sketches are not provided, I cannot determine the exact direction of the net force for each case. However, by following the steps outlined above, you can analyze each sketch to determine whether the net force on the green object is to the left, to the right, or if there is no net force.
