The figure shows four identical conducting spheres that are actually well separated from one another. Sphere W (with an initial charge of zero) is touched to sphere A and then they are separated. Next, sphere W is touched to sphere B (with an initial charge of −26e) and then they are separated. Finally, sphere W is touched to sphere C (with an initial charge of 50e), and then they are separated. The final charge on sphere W is 20e. What multiple of e gives the initial charge on sphere A? A B C W Number Units

Two objects are identical and small enough that their sizes can be ignored relative to the distance between them, which is 0.175 m. In a vacuum, each object carries a different charge, and they attract each other with a force of 0.970 N. The objects are brought into contact, so the net charge is shared equally, and then they are returned to their initial positions. Now it is found that the objects repel one another with a force whose magnitude is equal to that of the initial attractive force. What is the initial charge on each object, the answer to part (a) being the one with the greater (and positive) value? (a) Number Units (b) Number Units

Two objects are identical and small enough that their sizes can be ignored relative to the distance between them, which is 0.248 m . In a vacuum, each object carries a different charge, and they attract each other with a force of 1.32 N. The objects are brought into contact, so the net charge is shared equally, and then they are returned to their initial positions. Now it is found that the objects repel one another with a force whose magnitude is equal to that of the initial attractive force. What is the initial charge on each object, the answer to part (a) being the one with the greater (and positive) value? (a) Number Units (b) Number Units
