Homework Answers
Ans: 0, 0 (both uncharged)
When the positively charged insulator is brought close to the two metal spheres in contact, negative charges move to the left leaving the right sphere with a net positive charge. When the positively charged insulator is removed, the two metal spheres equilibrate since they are still touching. Negative charges will flow to the right sphere until neither sphere is charged. When the two spheres no longer touch, both are uncharged.

Two positively charged metal spheres are suspended from the same hook by light strings of equal length, making an angle of 10.0 degree with each other. The charges carried by the spheres are as shown in the diagram. After that, the spheres are brought in contact briefly, then released. If the mass of each sphere is 4.00 g, calculate the length of each string. the new angle theta between the two strings.

Consider the following experiment with a positively charged rod and two identical conducting spheres: • Step I: A positively charged rod is brought near, but does not touch, two identical conducting spheres in contact, where one of the spheres is closer to the rod than the other. • Step II: One of the spheres is grounded, and then the connection with ground is broken. The spheres remain in contact through this process. • Step III: The rod is removed. •...
