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. For 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.

The diagram below shows a positive point charge placed near a neutral metal cube. The location marked with a × can be ignored. a. Draw the charge distribution within the metal cube and reduce it to an “effective point charge model, as shown in class.b. Is the positive point charge attracted to, repelled by, or unaffected by the metal cube? Please explain using a neat vector diagram to support your arguments.c. In a second identical experiment, the positive point charge +q is replaced by a negative point charge −q. Does a negative point charge interact differently with the metal cube as compared to the positive point charge? Briefly explain your reasoning.

The sketch below shows three objects with electric charge. (The charge of each object is written on it.) Decide whether there is a net electric force acting on the central object. If there is, select the button under the sketch that shows the direction of this force. If there is no net force on the central object, select the center button. -2 O -2 -3

A small sphere with a mass of 0.450 gram is suspended by a non-conducting silk thread as shown. The sphere is subject to an electric field of 3000 N/C directed to the left and the sphere swings out 8° from the vertical as shown below. Follow the steps below to determine the magnitude of the charge on the sphere. A. e = 8° 1. Label all the forces acting on the small sphere on the diagram on the left. 2. Using the forces on your diagram determine the charge (magnitude and quality (+ or - )) on the ball.

RELATIONSHIP OF ELECTRIC FORCE, ELECTRICAL CHARGE AND DISTANCE OF CHARGES. DIRECTION: Choose the correct term in the parenthesis 1. The magnitude of distance of charges is ( inversely proportional , directly proportional) to the electrical force. 2. If the charge of both particles is doubled, the force ( unchanged, halved, doubled, quadrupled) 3. If the charged of one of the particles id doubled, the force is ( unchanged, halved, doubled, quadrupled) 4. If the distance between the particles is doubled, the force becomes ( one fourth, half, double, 4 times) 5. The product of charges is ( inversely proportional , directly proportional) to the electrical force.
