A positively-charged plastic rod is brought close to (but does not touch) a neutral metal sphere that is connected to ground. After waiting a few seconds, the ground connection is removed (without touching the sphere), and after that the rod is also removed. The sphere is now A) negatively charged. B) positively charged. C) neutral.

Why is A correct?
A rod-shaped positively-charged insulator is brought near a conducting sphere, and the sphere is momentarily grounded as shown in Diagram I. The conducting sphere is then placed near a nonconducting plane as shown in Diagram II. Which of the following statements is true for Diagram II? a. The conductor has a negative charge and is attracted to the nonconducting plane. b. The conductor has a negative charge and is not attracted to the nonconducting plane. c....

A positively charged ball is brought near to a neutral conductor, polarizing the conductor. Then the conductor is grounded, which allows negative charge to flow onto the conductor. See below positat entnas a) Now the positive ball is taken away, and then the ground connection is removed. Is the final charge on the conductor positive, negative, or neutral? Carefully explain your reasoning. b) What if, instead, the ground connection is removed first. and then the positive ball is taken away?...

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. •...

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...
