You touch a metal sphere which is positively charged. Which of the following is a correct description of what happens next? (Select all options that you think are correct) 1. As opposite charges attract and your body is a reasonably good conductor, some negative charge (if mobile) from your body is attracted to the metal and reduces the net positive charge on the metal. In the process you acquire positive charge. 2. As like charges repel and your body is...

Hw3 Problem 3.45 Review Part A The figuro Figure 1) shows four electrical charges located at the comers of a rectangle. Like charges, you will recall, repel each other while opposite charges attract. Charge B exerts a repuisive force (directly away from B) on charge A of 2.1 N.Charge C exerts an attracdtive force (drectly toward C) on charge A of 4.2N. Finally, charge D exerts an attractive force of 14 N on charge A. Assuming that foroes are vectors,...

Will a penny be slightly more massive if it has a negative or a positive net charge? (Think very small!!) (a) It will be just as massive either way. (b) More massive if negative. (c) More massive if positive. A charged conducting object is brought close to a neutral insulating object. Which of the following is true? (a) The objects will repel. (b) The objects will attract. (c) Nothing will happen, no attraction, no repulsion. (d) The objects will repel...

Which of the following statement is correct about the electric field on the surface of a charged conductor in electrostatic equilibrium? Group of answer choices It is parallel to the surface so that charge can move along the surface. It is perpendicular to the surface so that charge in the conductor cannot move along the surface by the electric field It is perpendicular to the surface because there are charges inside the conductor. It is perpendicular to the surface because...

5 Charges on a Line 02 Due in 7 hours, 23 minutes The following 5 charges are all on a straight line. Evaluate the direction of the forces listed. Note that these forces are specifically the force of one charged object on a different charged object, not the force from all of the charged objects on another. If the force is zero, select No Force. +,-and 0 represent positive, negative and neutrally charged objects, respectively. 3 2 4 5 Left...
